I assume this could still happen at https://github.com/nextcloud/text/blob/master/lib/Service/DocumentService.php#L391 where we should handle the case when a file is no longer there more gracefully.

[julien-nc]

@enoch85 Does this still happen? If so, could you provide a procedure to reproduce the issue?

Feel free to reopen the issue if you answer 😁.
