Errors, Limits, and Unavailable Actions

In LadVen OS, task restrictions are not only for security. They protect the work process: they prevent closing a task without a result, changing someone else's agreement without permission, losing a file, overwriting another participant's edit, or mass-changing tasks the user cannot access.

If the system does not allow an action, it is not always a technical error. Often it is a signal: the task is missing data, the action requires another role, the process forbids the transition, or a conflict must be resolved first.

Main rule: do not bypass a restriction through private messages, duplicate tasks, or verbal agreements. First understand what exactly is blocked, why it matters for the process, and who can make the decision.

The diagram treats a restriction as a recovery route: action, blocking reason, missing condition, and a repeat check of the result.

One-minute Quick Diagnosis

When an action does not work, first separate a process restriction from a failure. This saves time and helps avoid unnecessary duplicate tasks.

1. Read the LadVen OS message again: it usually points not only to the error, but also to the missing condition.
2. Check your role in the task: requester, assignee, co-executor, observer, or non-participant.
3. Check the task status: new, in progress, under review, closed, canceled, or limited by process.
4. Open the block related to the action: files, checklist, participants, details, comments, time, or links.
5. If the action is bulk, inspect one task where the action did not apply instead of the whole selection.
6. After correction, repeat the same action and make sure the result appears in the card or activity history.

Do not start with "why is the system broken?" Start with "which condition is missing for the next process step?" In task work, this usually leads to the correct recovery route faster.

What the Interface Shows

Restrictions can appear in different places. Read both the message text and where it appears.

What the user sees	What it usually means	First action
Button is disabled	The action is unavailable because of role, status, or a required condition	Check role, status, and the hint near the button
Button exists, but a warning appears after click	A process guard check stopped the action	Read the missing condition and correct the card
Field cannot be changed	Not enough permissions, task is closed, or change is forbidden at this stage	Check edit mode and decision owner
File is visible but does not open	No access, unsupported format, or outdated file	Try download, then check version and access
Files block shows File not attached	The selected file did not enter the task	Check filename and reason, then choose Retry or Remove
List is empty	Filter, saved view, permissions, or loading hid tasks	Reset filters and check access
Bulk action completed partially	Not all tasks fit the same decision	Review unapplied tasks separately
Old version is visible after save	Card is stale or there was an edit conflict	Refresh the task and compare history

If several signals appear at once, handle them in order: access first, then status, then required conditions, then temporary upload or network errors.

How to Read an Error Message

For any error or unavailable action, ask four questions:

1. What action was I trying to perform?
2. What exactly failed: open, save, upload, close, assign, change status?
3. Is this a permission restriction, process restriction, data issue, or temporary failure?
4. What should happen next: fill in a field, request access, refresh the page, write a comment, contact a manager, or contact an administrator?

Not every message is detailed. If the interface shows a short warning, reconstruct the context from the task card: status, user role, participants, files, checklist, comments, activity history, and permissions to related context.

Who Should Act

Not every issue should be fixed by the person who first saw the error. In LadVen OS, route the question to the right role quickly.

Situation	Usually resolved by	What to record in the task
Missing result, file, or completed checklist	Assignee	What was added and where the result should be checked
Acceptance or return for rework is needed	Requester (Reporter role) or reviewer	What was accepted, what should be returned, and why
Another assignee or participant access is needed	Manager or requester	Whom to add, in which role, and why
Process rule does not fit the case	Process owner or administrator	Example task and why the rule blocks normal work
Bulk action did not apply to part of the selection	User who launched it or slice manager	Which tasks were not changed and the reason for each group
No access to client, project, document, or file	Context owner or access administrator	Which object is needed and for what work

A poor request says "it does not work." A good request includes the action, task, visible message, already checked conditions, and expected decision.

No Access to a Task

No access means the user cannot open the task or sees it only partially. Possible reasons:

• the task is in a project, workgroup, client, or CRM context with restricted access;
• the user is not a task participant;
• the link points to a task that was deleted, moved, or hidden;
• the user role does not allow seeing part of the data;
• an external participant has no access to internal materials;
• the task is linked to a document or client not available to everyone.

What to do:

1. Check whether you are opening an outdated link.
2. Clarify with the requester or manager whether you should participate in the task.
3. If access is needed for work, ask to be added to the task with the correct role.
4. If you need a file, client, or CRM record, request access to the exact needed source, not only to the task.
5. If you are a manager, check whether the process is configured so required tasks are hidden from responsible people.

Do not ask someone to forward task contents to a private chat as a permanent solution. The task stops being the single source of agreement, and the work history fragments.

Button or Action Is Unavailable

A button can be hidden or blocked if the action is currently inappropriate for the role, status, or process.

Typical reasons:

• the user has no permission to edit the task;
• the task is already closed or canceled;
• the task is under review, and the action is available only to the requester or reviewer;
• a required result, file, comment, or completed checklist is missing;
• a guard check is enabled before the status transition;
• the action is available only to the assignee, requester, or process administrator;
• the selected bulk action cannot be applied to some of the tasks.

What to do:

• hover over the button or read the hint if one exists;
• check the task status and your role;
• see whether required fields must be filled in first;
• open comments and history: another participant may already have performed the action;
• if the action is really needed, write a comment in the task and ask the process owner to perform or allow it.

Good task comment:

I cannot close the task: the system asks for the final file. I attached the current version in a comment and ask the requester to verify and confirm closing.

Poor practice:

I cannot click it, close it somehow.

This does not explain what blocks the process.

Guard Check Before Closing or Status Change

A guard check blocks an action if the task is not ready for the next stage. For example, a task cannot be closed without a result, sent to review without a file, completed as a client task without a comment, or moved to another status without a required field.

This check keeps process quality from depending only on a participant's attention.

In the interface, this looks like a blocked action: the user clicks close, send to review, change status, or start rule, and LadVen OS shows a clear message. A good message does not only say "not allowed"; it explains:

• which action was stopped;
• which condition is missing;
• what to add or correct;
• who can help if the user has no rights to fix it;
• that the same action should be repeated after correction.

In a task card, this message should stay near the working actions instead of disappearing like a system popup. That lets the user open the right block, show the issue to a manager or assignee, and take a screenshot for process review. If Open details is available, use it to go to the required field or block. If the system asks for a planned estimate, use Set estimate.

For process review, the screen should show the blocked action, the missing condition, where to fix it, and the next available step. Do not treat a screen as good working evidence if it only shows a temporary popup, a technical code, an internal error name, or a reason without a recovery path.

If a guard triggers:

1. Read which condition is not met.
2. Find the missing element in the task card: file, comment, checklist, estimate, assignee, link, field, or confirmation.
3. Correct the task yourself if it is within your role.
4. If another person must correct it, write a task comment and state exactly what is missing.
5. If the condition does not fit the current case, contact the process owner or manager instead of bypassing the check with a duplicate.
6. After correction, repeat the same action and verify that the status changed or the task moved to the next stage.

Examples:

Blocked action	Missing condition	Who fixes it	How to repeat
Closing the task	No final file or result link	Assignee attaches it, requester checks	Save the file and click close again
Sending to review	Result owner is not assigned	Requester (Reporter role) or manager assigns the responsible person	Save participant and send to review again
Status change	Required checklist items are incomplete	Assignee completes items or explains an exception	Update checklist and repeat status change
Rule launch	Task is outside rule scope	Process owner clarifies the rule or task	Correct the condition and launch again

For a manager, the important part is not only the block itself, but the reason. If a check often gets in the way of normal work, it may be too strict or may not explain how to fix the task.

If the same block appears for several employees, it is already a process signal: the template may be missing a required step, the guard message may be unclear, or the rule may require data that the team cannot provide during normal work.

Fixing a Block Without Losing Meaning

A guard check should not be treated as a formality to bypass. The fix should preserve the task's working meaning.

Block reason	Poor fix	Good fix
No final file	Attach a random draft just to close the task	Attach the current version and state what counts as the final result
Checklist is incomplete	Mark every item done without checking	Complete ready items and explain exceptions in a comment or related task
No assignee	Assign the first available employee	Assign the result owner and add helpers as co-executors
No return comment	Write "redo"	State the concrete issue and expected correction
Rule does not fit the case	Create a duplicate outside the process	Record the exception and pass the example to the process owner

If the current task truly no longer matches the work, create a related task, not an unrelated duplicate. The history then remains understandable: what was accepted, what became new scope, and who owns the continuation.

For tasks with a required final file, the guard should lead the user to restore the result rather than bypass the process. If the file did not upload, first handle the attachment error: filename, size, format, access, Retry, or Remove. After successful attachment, return to the original action and send the task to review, accept it, or close it again. See Review and close a task and Attach files.

Edit Conflict

A conflict appears when several people change a task at about the same time. For example, one participant moves the deadline, another edits the description, and a third adds a file or participant.

The main risk is losing another person's edit or saving an outdated agreement over a newer one.

Correct order:

1. Stop and do not save changes automatically.
2. Refresh the task or compare what changed.
3. Keep only the actual current edits.
4. If the changes affect deadline, scope, assignee, or acceptance, record the final decision in a comment.
5. After saving, check the card in view mode.

If the conflict concerns an important agreement, leave a short comment:

Updated the task after an edit conflict: deadline remains May 27, the current file is the May 20 version, assignee is unchanged.

This tells the team which version of the agreement became final.

Save Error

A save error can appear when creating a task, editing, adding a comment, changing a checklist, time, or participants.

Before trying again, check:

• required fields are filled in;
• the connection was not lost;
• the card did not become stale after a long edit;
• another participant did not change the task;
• file, text length, or selected element limits were not exceeded;
• you have permission for this action.

Do not press save many times in a row. If the action has already been sent, wait for the result. Repeated clicks can create duplicate comments, files, or time records if the system has not yet shown the state.

If the error repeats, record in the task or tell the administrator:

• what you tried to do;
• which task was involved;
• which fields were changed;
• which message appeared;
• whether the error repeats after refreshing the page.

Comment Did Not Send

A comment is added to the feed immediately and delivered in the background. If sending fails, the message does not disappear: it stays visible with an error mark and a retry button.

What to do:

1. Do not write the comment again — the text and attachments are already saved in the unsent message.
2. Check the connection and wait until the indicator stops showing "sending".
3. Press retry on the comment itself.
4. If the attachment is large, wait for its progress: the comment counts as delivered only after the "sent" indicator.
5. Before closing or accepting the task, make sure no comment is stuck in an error state.

If retry does not help, copy the text to a safe place, refresh the task, and tell the administrator which task and which action caused the comment not to send.

File Upload or Open Error

Task files may fail to upload or open for several reasons:

• the file is too large;
• the format is not supported for preview;
• the connection was interrupted during upload;
• the user has no access to the file or drive;
• the file was deleted or replaced;
• the link points to an outdated version;
• the file is attached to a comment or checklist item, but is not visible in the needed filter.

What to do:

1. Check whether the file is visible in the files block, comment, or checklist item.
2. Try downloading the file if preview does not open.
3. Clarify which version is current.
4. If the file is needed for acceptance, ask the executor to attach the final version in a separate comment.
5. If access is missing, request access to the file or related drive.
6. If upload failed, retry after checking size and format.

If LadVen OS shows an error near the selected file, do not close the message before checking the reason. First make sure it is the correct file, then decide whether to Retry upload, Remove it from the list, or replace it with the correct version. For acceptance, the final material must be actually attached, not only selected on the user's computer.

For important materials, write an explanation:

The final version for review is `contract-v3`. The old file is kept only for history.

This prevents disputes over which file is the working version.

Cannot Assign a Participant

Employee selection may be unavailable if the person is not in the needed department, has no access to the workgroup, client, or project, is disabled, is restricted by role, or cannot be selected as an external participant.

Some people are not just unavailable for selection — they do not appear in the candidate list at all. Participant search shows only active internal employees who are allowed to take tasks into work, so external (guest, extranet) and disabled accounts do not appear in it. If a person is not in the list, this is expected behavior, not an error: make sure they are an active employee with task permissions, and clarify access with an administrator if their participation is really needed.

Before assigning, check:

• which role the person should receive: assignee, co-executor, or observer;
• whether they need access to project, client, CRM, or files;
• whether mentioning them in a comment is enough for a one-time question;
• whether the assignment blurs responsibility;
• whether they can see related materials.

If the employee cannot be selected, do not assign a random person instead. Clarify access with the manager or process administrator. You can leave a comment in the task:

Olivia needs to be added as a co-executor, but she cannot be selected in participants. Please check access to the workgroup and client project.

Bulk Action Completed Partially

Bulk actions are useful when the same change must be applied to several tasks: assign a person, change a deadline, add a tag, update a status, or apply another identical decision.

A partial result means the action was not applied to all selected tasks. Reasons:

• some tasks are closed or in an unsuitable status;
• the user has no permissions for some tasks;
• a guard blocked some changes;
• separate tasks were changed by another participant;
• one or more tasks did not meet required conditions;
• some related context are unavailable.

What to do:

1. See which tasks received the action.
2. Open tasks where the action failed separately.
3. Do not repeat the bulk action on the whole set without checking.
4. Fix the reasons: access, status, required fields, conflict, or guard.
5. Repeat the action only for remaining tasks if it is truly the same decision.

A bulk action must not replace a management decision. If tasks differ by context, deadline, or assignee, review them separately.

Reading a Partial Result

After a bulk action, a manager or assignee should understand not only the number of successful tasks, but also the reason groups.

Group	What it means	What to do
Changed successfully	Tasks passed conditions and permissions	Check the slice to confirm they moved to the needed state
No permission	The user cannot change part of the tasks	Pass the list to the slice owner or request access
Status does not fit	Tasks are closed, canceled, or on another stage	Do not repeat bulk; open these tasks separately
Guard triggered	Required condition is missing in tasks	Add missing files, checklist, comments, or participants
Edit conflict	Data changed during the operation	Refresh cards and make the final decision manually

Do not run the same bulk action again on the same selection "just in case." It can change already processed tasks again and confuse the history.

Automation Did Not Run or Ran Differently

Automation can create a task, change a field, add a comment, assign a participant, start a recurring process, or block an action. If the result differs from expectations, look not only at the current card, but also at history.

Check:

• whether the rule or recurring task is enabled;
• whether the task matches rule conditions;
• whether automation is disabled for this process;
• whether a duplicate prevented a new task from being created;
• whether automation history has an entry;
• whether a person changed the task after the automatic action;
• whether the comment or event created by the rule is clear to the user.

If automation gets in the way, do not silently disable it. Record an example task and the reason:

The rule added an observer after moving to review, but another department reviews this process. The condition needs clarification for tasks tagged `implementation`.

This lets the process owner fix the rule without breaking other scenarios.

If the rule is not enabled yet, open preview first. It is not a promise that "everything will be fine"; it is the list of future consequences: which tasks will match the rule, which actions will run, which tasks will be skipped, and why. If preview shows extra tasks, do not enable the rule until the scope is clarified.

If the case is a recurring task, check it as a process:

• schedule and time zone;
• process owner;
• template used to create the task;
• deadline of the new task;
• duplicate policy;
• launch history: created, skipped, blocked, completed with an error.

If a recurring task did not appear because of an active duplicate, review the previous task first. If it appeared one time too many, check the schedule and duplicate policy, then leave a comment in the extra task before canceling it.

Task Looks Empty or Data Does Not Update

Sometimes a user sees an empty list, empty comments, missing files, or an old status. This does not always mean the data is absent.

Check:

• active filters and saved views;
• selected view;
• access rights;
• whether closed or archived tasks are hidden;
• whether old comments or events loaded;
• whether an outdated screen is open after a long pause;
• whether another participant changed the task.

If the task list is empty, reset filters first. If the card looks incomplete, refresh it and check history. If the data still is not visible, clarify access.

What to Write to a Manager or Administrator

A good request helps quickly understand the problem and avoids a chain of follow-up questions.

Specify:

• what you tried to do;
• in which task or view;
• which message you saw;
• what you already checked;
• whether an urgent management decision is needed;
• who is blocked by the problem.

Example:

I cannot send the task to review. The system asks for a final file, but the file is already attached to a checklist item. The task is needed today for client result acceptance. Please check whether the file must be attached directly to the task or whether checklist attachments can be counted.

This request contains the action, reason, context, and expected decision.

How a Manager Should Review Repeated Errors

If the same block appears for different employees, it is no longer only a user issue; it is a process signal. Managers should look for repetition.

Check:

• which tasks have the restriction: client, internal, template-based, recurring, urgent;
• who encounters it most often: new employees, a department, reporters, assignees, reviewers;
• which stage is blocked: creation, execution, review, closing, or bulk change;
• whether the interface message is understandable without separate explanation;
• whether the template has the needed fields, files, checklist, and roles;
• whether the rule requires data the team cannot obtain before doing the work.

After review, choose one practical route:

• clarify the task template;
• add a required checklist item;
• improve the instruction or guard message;
• relax the rule for exceptions;
• train the team on the correct workflow;
• split one broad process into several scenarios.

This is how LadVen OS helps improve the operating system of the business: repeated failures become clear rules and templates.

Good Practices

• Read a restriction as a process hint, not only as an obstacle.
• Do not bypass guard checks with duplicate tasks.
• When an edit conflict appears, refresh the card first and then save the final agreement.
• For file errors, clarify the current version and access.
• Use bulk actions only for tasks with the same decision.
• Record important problems in the task so the history is not lost.
• If a restriction repeats for many employees, review the process or rule.
• After fixing an error, verify the result in the card: status, file, comment, participants, history.

Common Mistakes

Mistake	Why it is dangerous	Correct approach
Bypassing a restriction in a private message	The decision does not enter task history	Record the reason and next step in a comment
Creating a duplicate instead of fixing the current task	Work splits into several unrelated cards	Fix the blocking reason or create a related task with an explanation
Pressing save repeatedly	Duplicate comments, files, or time records may appear	Wait for the result and check the state
Bulk-changing different tasks	Deadlines, responsibility, and context can be broken	Use bulk only for identical decisions
Ignoring a partial result	Some tasks remain in the old state without attention	Review unapplied tasks separately
Treating missing data as fact	A filter, access, or loading issue may hide information	Reset filters, refresh the card, check permissions

Quick Diagnosis

What failed	What to check first	Where to look next
Open a task	Access, link, participation in the task	Requester (Reporter role), manager, administrator
Change a field	Role, status, edit mode	History, permissions, edit conflict
Close a task	Result, files, checklist, review	Comments, guard checks
Upload a file	Size, format, connection	Drive access, current version
Assign a person	Role, access to project or client	Department, workgroup, administrator
Perform a bulk action	Whether selected tasks have the same decision	Partial result, permissions, statuses
Understand automation	Rule history, condition, process owner	Automation page, comments in the task

Which Restriction States to Understand

The important part is not the error message itself, but the working context: what stopped, why it protects the process, and which action returns the task to normal flow.

Scenario	What the user should notice	What to do next
Guard check before closing or status change	Missing condition and action to repeat after correction	Add the result, file, checklist, or comment, then repeat the action
Partial bulk result	How many tasks changed, how many were skipped, and why	Review skipped tasks separately instead of rerunning bulk blindly
Edit conflict	The card changed after opening or before saving	Refresh the card, compare the agreement, and save the current version
Action unavailable because of permissions	Role, status, or access does not allow the action	Request the needed role, participant, or access to the related object
File error	The file was not uploaded, cannot be opened, or is unavailable for review	Check version, format, access, and retry upload when needed
Empty list because of a filter	The active slice hides tasks	Reset or refine filters before deciding there are no tasks

Before discussing an error or guard message in training, support, a report, or with a customer, anonymize the data: real clients, phone numbers, email addresses, contracts, private links, and internal comments must not be visible.
