Jellyfin- unable to set up media libraries after initial deployment

Apps and Virtualization
1

Hi,
I’m running TrueNAS SCALE ver ElectricEel-24.10.2.3 and have installed jellyfin docker app from the community train (app version: 10.10.7, ver: 1.2.5). The app starts up successfully and then when stepping through the initial app set up wizard, the app hangs on “Set up your media libraries”.

From the log, I’m getting this error:
[ERR] [8] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: Could not find a part of the path ‘/config/root/default’. URL GET /Library/VirtualFolders.

I have configured additional ‘host path’ storage for the app (for the media libraries):
mount path: /media/tv
host path: /mnt/tank/mediavault/Tv

The TrueNAS in-built ‘apps’ user has rights to the container and to the host-path. It seems because of the error the app is unable to mount the media path and therefore hangs.

Any hints on what could be the cause of the error and how to resolve?
I have tried deleting and re-installing the app without luck.

Note: All storage configuration paths are user-defined i.e. host-based paths (/mnt/apps/jellyfin).

Thanks a lot!

Sorry a short addendum, from the container shell, I can actually see that it has mounted the additional storage (/media/tv) as expected.

I suspect that the error is still related to the app hanging at step “Set up your media libraries”.

Thanks again.
