[BUG] Facial recognition does not work - incorrect file path

The bug

Hello together,

I installed immich on my Synology NAS 920+ with Portainer based on this tutorial: Link

It is a quite standard Docker installation with the standard immich env. File.

Everything works absolutely fine -except for the image recognition.

immich-microservices throws the following output:

The thing is: the file: upload/thumbs/61ec5320-1d8a-4421-a0d8-cc4f0e70d5e5/62dd6c44-6f5d-4b3a-8c94-17ecf419c238.jpeg exists - I can navigate to it in my folder path and everything else on the immich installation works just absolutely fine (including tagging, uploading, deleting, etc...)
