While I can see in the code what triggers this error message I can't quite understand when this code path is triggered.

Does this happen for any file? Or are they in subfolders or do you try to restore folders? Would be awesome if I would be able to reproduce this locally.

I know whats the Problem or how you can reproduce it.

I have deleted a file (picture) from the root. If I click on "Wiederherstellen" (restore file) in the same line behind the file Name -> no error occurs.
But if I select the file and use the button above the table -> error is logged.

Here a screenshot with a Little documentation what I've do.

Thanks for your reply!
