I was having the exact same issue and was able to fix it by setting username, user_id and token. I found the user_id best by using jellyfin-web and being in the profile settings of that user either as admin or user itself.

When I didn't set libraries, Everything but Albums and Tracks worked, otherwise:

https://github.com/jellyfin/mopidy-jellyfin/blob/30a09c3c4018ca38749f313ad7dc35eb70f4908f/README.rst?plain=1#L48

Weirdly enough Tracks is still empty for me.

Maybe the Readme should have the Optional for user_id and token removed. As without token:

Exception: No authentication token found

and with token but without user_id the aforementioned:

TypeError: 'NoneType' object is not iterable

This issue has nothing to do with authentication method. This is because the released version was specifically looking for a "playlists" library that the user may or may not have created yet, and was fixed in #136. Version 1.0.5 has now been released that should include this fix
