I was getting "error creating playlist” in Jellyfin. I installed it through the app center. I have an SSD as volume 2 for docker so that the raid drives can sleep.
The fix was creating a folder docker/configurations/Playlist. (the docker/configurations part already existed in shared folders).
This isn’t a huge deal, just figuring out where to create the Playlist folder is a chore. If possible, might want the app center to create that folder automatically when you install Jellyfin.
Thanks
