Describe the Bug

According to the logs, recognize cannot get the root storage and does not provide a detailed error, so my guess is that it's failing on here: https://github.com/nextcloud/recognize/blob/d8719ff2742ade14e2fe9821da9c2f676871166b/lib/Service/StorageService.php#L118

For some reason, root is false.

Expected Behavior

Recognize properly detect the root storage and scans the images.

To Reproduce

1. Install app through the store
2. Run sudo -u www-data php occ recognize:download-models to download models
3. Enable people recognition
4. Fails

I don't know why this would ever happen. Could it be that your nextcloud instance is b0rked somehow? Are you doing anything special?

I've got the same error

What can help ?

Edit : i just restarted php-fpm and everything seems to work.

I have same issue. I will try to restart docker container.

Still it throws the error. I am running nextcloud by docker-compose. Having the external storage mounted thru NFS from Proxmox to VM, then by local in NC. Not sure if it is connected with the issue. Everything else is working fine.

I have been having this issue since April on NC 26. Now on NC 27.1.2, it persists. Recognize does not scan or detect faces, I have reset it and tried to rescan but no luck. "Could not fetch storage root" is the only error in the logs. My NC has always worked, and is still working 100% fine otherwise.

Also have been experiencing this issue. Classify works fine from command line, but background jobs always seem to trigger this error. Bare metal box ubuntu 22.04 and the files are not in external storage. NC 27.1.2 and Recognize 5.0.3

[beckenc]

Same here. Running in a docker container via docker-compose. External storage is mounted via CIFS to nextcloud

[marcelklehr]

This should only ever be temporary, I believe. I have not found a way to reproduce this consistently
