All songs disappeared from playlist

[AK-47]

I'm running Jellyfin 10.10.0 on Windows 11.

I only have one music playlist in Jellyfin. I went to play it today, for the first time in just under a year (it is a Christmas music playlist), but when I tried to play it, I realised none of the songs appear in the playlist - but the duration of the playlist still shows in Jellyfin, and the tracks can be played individually from Jellyfin, so I know they haven't been deleted.

I have attached what I see when I view the playlist in the web interface. You will see it still lists the duration of the playlist (6h 4m), so the playlist *should* still be intact somewhere.

I have no idea at what point or with which update of Jellyfin the songs disappeared from the playlist, but it would be somewhere between December 2023 and now.

How do I troubleshoot this? As there are no songs appearing, I can't attempt to play one, so I don't think the log will show anything.

Thanks in advance.

Can you restart Jellyfin and then after it finishes restarting share your jellyfin log via pastebin?

Also, how is your media stored? On a local hard drive or on a NAS?

Thanks for the response.

The Pastebin of the log is here: https://pastebin.com/C7VbHsyt

The media is all stored on a local hard drive.

EDIT: I just updated to 10.10.1. It made no difference except the duration (6h 4m in the previous screenshot) has now disappeared. Attached is how it looks now.

The log is pending moderation. Can you zip the log and attach it to a forum post?

Sorry, updated log attached

There is nothing in the log.

What probably happened is that at some point in the last year the files for your Christmas Music were unavailable during Jellyfin startup. There is a job, that only triggers on startup, that will examine your playlists and collections and remove items that are no longer present. If your D drive was unavailable it would have cleared out that entire playlist.

Thanks. Yes there was at least one occasion Jellyfin started up when the D drive wasn't connected.

I understand the Playlist disappearing whilst the drive isn't connected, but why wouldn't it just re-appear when Jellyfin is next started with D drive connected, like it does the media itself?

Is there any way to avoid this behaviour? Or at least mitigate the impact, e.g. is there a playlist file I can back up somewhere and just paste it back to the original location if this happens again? Jellyfin loading up without at least one of the drives present is likely to happen again at some point in the future,

Once it clears the playlist/collection, its gone. You can disable the scheduled tasks. Dashboard > Scheduled > Cleanup collections and playlists. Open that up and delete the startup trigger.
