Navidrome: Navidrome won't show cover art from external files

[TheForcer]

After now having updated to 0.24, Navidrome does not seem to fetch external Cover Art files for me and shows the default blue vinyl. Most of my collection consists of FLAC files with no embedded image files, but cover.jpg files in the album directories. The albums with embedded artworks show up fine.

For further testing, I also set the ImageCache option to 0 and priority as well in my compose file, but that did not help.

ND_IMAGECACHESIZE: 0
ND_COVERARTPRIORITY: "cover.*, folder.*, embedded"

Got an idea what could help?

Typical request would look like this:

What was your previous version? Was it displaying the cover arts correctly? If it was, what was the value of ND_COVERARTPRIORITY?

[TheForcer]

Previous version was 0.22, it didn't show any cover art since only 0.24 supports external cover art files. However, embedded cover art files were shown correctly.
I only added the cover art priority setting to debug the issue on 0.24, it was previously unset/left to default.

[deluan]

Ah yes, my bad: it was introduced in 0.24!

Did you rescan the library? A full rescan is required, as covers are detected during scan. I just released 0.25.0, that has experimental support for forcing a full rescan. Just execute: docker-compose run navidrome scan -f

Let me know if this is the issue and if it helps you

[TheForcer]

Ah, alright, didn't know about the required scan.
Will update and re-scan :)

[TheForcer]

The rescan did indeed fix the issue, all the cover arts are now showing up.
Thank you very much for your help as always 😀
