[Bug] Lidarr: Failed to Fetch Artists

StormPooper commented 3 years ago

Describe the Bug When I attempt to access the Artists tab in Lidarr, I get an error and a retry prompt. Looking at the logs, I get the following:

Error	Lidarr: Failed to fetch artists
Class	package:lunasea/modules/lidarr/core/api/api.dart
Method	LidarrAPI.getAllArtists
Exception	NoSuchMethodError: The getter 'name' was called on null. Receiver: null Tried calling: name

To Reproduce Not 100% sure, happened consistently since I installed it, but only just found the log section in Settings. Looking at the code mentioned, I suspect it is failing to get quality or metadata (which is odd as you're checking if it is null before checking accessing name on it), but as far as I can tell they should all be set. My only potential theory is I have the "Various Artists" special artist in my list with metadata set to None, but I've tried changing it to Everything to no avail. Every artist has been set to the same quality profile (manually confirmed this by setting it again in the Mass Editor).

Expected Behaviour A list of my artists.

Versions LunaSea: 5.1.0 (50100004) Android (Google Play) Lidarr: 0.8.1.2135

Additional context Radarr and Sonarr working with no issues with similar configuration (LinuxServer.io Docker containers). I'm able to add artists and the Missing/History tabs work with no issues.

Thank you for the detailed breakdown, I will definitely investigate this for the next release!

No problem, let me know if you want me to test any builds against my library.

As part of a library cleanup, I changed a few artists to have a metadata profile of None and deleted a couple of artists. It's now working perfectly in LunaSea, so unfortunately I won't be able to test any changes.

My guess is somehow one of the artists had literally no profile rather than the None profile, but I doubt I can get it back into that scenario as it was probably from a much older build, since most of the artists I changed had been in my library from the start.
