A task is missing, duplicated, or cannot be updated

Check view scope and the original task before creating another record.

If a task is missing, open the project’s All Tasks view and clear filters. Check assignee and status filters, canceled-work visibility, and any canvas scope on the Board.

If a task appears in more than one place, compare its identity and home project. A task on Canvas, Board, All Tasks, or a pinned reference can be the same task shown through different views. An external CSV or JSON import, however, creates new tasks.

If an update fails, check the project’s write permissions and task assignment policy. For a pinned task, check the home project’s rules.

After an import, read the result summary and warnings. Check date parsing and assignee mapping on a sample before proceeding with more data.

Escalate with the task link, relevant project and view, active filters, and the error message.
