Solve unknown fields error in the audit log

The error Unknown fields set during edit. Field may not be available project/type. is caused during a create, edit or transition issue action because the field you are trying to edit is not on the Jira screen, or the rule actor doesn't have permission to access/edit that field. This isn't something that can be validated when the rule is being configured.

Solution

*note, to do this you must be logged in as a Jira administrator and this doesn't work for sub-tasks

  1. Go to one of the issues that triggered this error (follow the link in the audit log)
  2. Open the edit issue dialog (if you are using the 'edit issue' action) or open a new issue (if you are using the 'create issue' action)
  3. Click the "fields" button in the top right hand corner, and then "Where is my field ?"
    Where is my field
  4. In the following dialog, type the field you are trying to edit
  5. Jira tells you of any issues to fix to make it editable
