Describe the Bug

It seems that when using S3 as main storage, recognize can't access the files.
When using occ recognize:classify just after enabling face recognition, it spams Could not find file and removing 123456 from faces queue because it couldn't be found and only succeed to run on images hosted on my SFTP external storage, not on files hosted on S3 main storage.

I've ~600 photos.

It seems to work when using regular background job though, only occ recognize:classify seems to have this problem.

Expected Behavior

It should detect faces also on S3 main storage.

To Reproduce

• Setup a Nextcloud with S3 main storage
  • Note : I use Hetzner CAX11 (ARM64) and Scaleway Object Storage.
• Add some photos
• (Add a SFTP external storage)
• Install Recognize
• Activate Face Recognition
• Run occ recognize:classify
• See that it succeeds only for images hosted on SFTP, not on S3

Debug log

Start with the occ recognize:classify entry point and the linked debug log, then compare its file access with the regular background job that succeeds. Reproduce the command against S3 main storage and SFTP external storage; done means classification can process images stored in S3 without Could not find file or removing queued items.
