List of steps to reproduce (step by step, including full links if applicable):
- Find a structured data edit (like https://commons.wikimedia.org/w/index.php?title=File:Editwar.png&diff=621282184&oldid=616178398)
- Undo, or restore from previous revision
What happens?: Returns an internal error. [7e825f2b-c0df-4234-be06-2fac381ffb7a] 2022-01-13 01:31:08: Fatal exception of type "LogicException"
What should have happened instead?: Reverted the edit with the edit summary I used
Workaround: Rollback still works, and using the structured data editor to revert also works too.
