Details

Automation rules to create issues will fail if a field set on the action is not available on the Create issue screen for the issue type on the project, throwing this error on the automation rule's audit log:

Unknown fields set during clone, they may be unavailable for the project/type. Check your custom field configuration. Fields ignored -
Custom field name (Custom field ID)

Problem

The error message is unclear, Jira Cloud contains a complex field configuration set up, it may relate to field configuration, field configuration schemes, or specifically the create issue screen.

Suggestion

Make the error message clearer on what is missing, and how to resolve it.
