I'm trying to delete a song from a jellyfin playlist by an API call. I use following DELETE request: When I execute this, the song doesn't get removed from the playlist and I get return code 204.

If I look in devtools network window and perform the action manually, I get the same request except for the api_key parameter.

When I perform the task manually, the song gets removed from the playlist. What am I missing here?

Another method I tried was editing the playlist xml file in /var/lib/jellyfin/data/playlists but that didn't seem to do anything either...

All other API calls work (including deleting a playlist). I already looked with wireshark and jellyfin actually receives the DELETE request.

I'm using Jellyfin version 10.8.8
OS: Linux
Architecture: Arm64

I found the following in the logs. Maybe this has something to do with it but I don't really know how i could fix this.
