Items in playlists cannot be moved. The item goes back in the interface back to its previous location and an error "Index was outside the bounds of the array" appears in the logs.

Description of the bug

After upgrading to 10.10.0, playlist items can not be moved. (Downgrading back to 10.9.11 solves the issues, so it seems likely due to the upgrade). I have previously had a similar issue where a playlist containing a removed item could no longer be rearranged or edited (that seemed like it was fixed). I tried creating new playlists, restarting the docker container, restarting the docker service and restarting the system. I also tried connecting through the local ip and http:// rather than through a nginx-proxy-manager and https://. Nothing solved the issue until I reverted the docker container to the 10.9.11 image.

Since part of the error in the logs said "Index was outside the bounds of the array," I tried moving an item to different places but all locations in a playlist led to the same error.

Reproduction steps

1. Create a playlist and add items.
2. Rearrange the items in the jellyfin interface.

What is the current bug behavior?

The playlist order does not change and an error appears in the logs saying " [ERR] [31] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request. URL POST /Playlists/c58b999842431004eb431fecfc2037f2/Items/be6a6882828d47dfba59eaa928003ca1/Move/0.
System.IndexOutOfRangeException: Index was outside the bounds of the array."

What is the expected correct behavior?

The playlist order changes.

I can reproduce this in 10.10.0 and also cannot delete playlist items.

[DickieKnee]

Also can not remove items in playlist

I'm having the same issue, but my logs don't throw any errors when I try to remove something from a playlist.

[pixel24]

Yes, I’ve been experiencing this bug since 10.10.0 as well, and it's been tough, especially because I spend a lot of time listening to music. I could technically roll back to version 10.9.11 on my PVE, but unfortunately, I only noticed the bug after adding a lot of new tracks to playlists. Now, I’d have to manually back up these playlists and merge them again after the rollback.

I'm really hoping this issue will be resolved soon.

[erictroebs]

Removing an item from a playlist does not raise an exception for me. Moving an item does.

JellyFin_log.txt
I will add my comment to this but. I just started using JellyFin and tried to sort my list by drag/drop and got the out of bounds error which makes the playlist not very useful for lists that need to be in order.

I am on 10.10.0 with a Docker image on a Synology NAS.

[erictroebs]

FYI: The bug is still present in the most recent version 10.10.1.

@RangerGH Use jellyfin/jellyfin:10.9 until the mentioned fix is merged into the next release.

[jc1bert]

Issue seems to be solved in 10.10.2 since Shadowghost's patch was merged.
