We have a rule that automatically sets the sprint on on issue given certain conditions.
The rule is configured to set the sprint to the active sprint of a board (which is available in the dropdown for the Edit Issue -> Set Sprint action).

The rule fails with the error:
No fields or field values to edit for issues (could be due to some field values not existing in a given project):

Initially, this failure seemed to be only for one of our boards. Now, it fails for all boards. I can manually set the sprint to the active sprint for that board. There is only one active sprint on each of those boards.
