Debug log

No response

Start by inspecting recognize/lib/Classifiers/Classifier.php at lines 105 and 291, then reproduce the scan with the reported Nextcloud, Docker, and storage setup. Check why the reported image paths are unavailable during classification and preview generation. Done means background scanning processes the affected pictures without these file or preview errors.
