I am not able to reproduce this.

[rainer-geiger]

I have exactly the same problem. Unfortunately I can't say exactly when and how it occurred, but I think it happened after a full media scan after checking the modification date of the files

All XML-playlists in ./config/data/playlists are empty:

ls -lah
-rw-r--r--  1 root root  324  6. Jun 21:05 playlist.xml

Nothing found in the logs for this timestamp...

I'm on Docker with version 10.9.4 now. I had the same problem with 10.9.3 and manually restored the XML files from a backup.

[Shadowghost]

Can you please check on 10.9.6?

[rainer-geiger]

Yes, I will test it tonight with 10.9.6 and report...

[Shadowghost]

It would also be helpful to get the playlist.xml (with all the paths in it) from before it got deleted if anyone has one.

I just tested it with version 10.9.6 and previously restored my XML-playlists from my backup. After a full media scan, the playlists are definitely still there. I will keep an eye on this over the next few days.

[jedthe3rd]

It would also be helpful to get the playlist.xml (with all the paths in it) from before it got deleted if anyone has one.

So for me the playlist xml files are not deleted. Just that the playlist itself is removed from the databases I guess and then any playlist xml files are not being readded. So maybe it is failing at re-adding the playlist xml files. If that is how it works in the code.

I had no playlists before 10.9.z

[jedthe3rd]

I am going to test removing all playlists in the data/playlists folder and running a media scan. Creating a playlist and rerunning the media scan.

Edit:
Same result

[4EverChaos]

I have the same issue that playlists are empty since 10.9.6, my playlists are .m3u files automatically created by MusicBee. A repeated scan of the library, playlist or updating the .m3u files, are not able to fill the playlists for Jellyfin again. All of that was able to help previously if it had problems.

Are all of you running Jellyfin on windows?

My Jellyfin instance is running on Ubuntu 22.04.4
