I think you found a remaining case that wasn’t covered by fix OC_Image: Prevent E_WARNING from getimagesize* by marcelklehr · Pull Request #36636 · nextcloud/server · GitHub

The issue is here probably:

Feel like testing? If it fixes you can submit a PR! :slight_smile:

Change this:

            $sizeResult = getimagesizefromstring($file->getContent());

To:

            $sizeResult = @getimagesizefromstring($file->getContent());

from repo and it’s working well now:
