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

It also outputs a bunch of warning in Admin > Logging, though it seems to work at least for some files when using the regular background job

S3 main storage

This means you've mounted your S3 storage as a local file system right? So, for Nextcloud the S3 storage looks like a normal fs?

[marcelklehr]

That exception means a local file cannot be generated, likely because it isn't available. I cannot tell you much more than that.

[Aeris1One]

No, S3 isn't mounted as a local filesystem. I use the native objectstore configuration in Nextcloud that allow to use S3 as primary storage. Here's the doc about that feature : https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/primary_storage.html
