Can't scrobble a song with "Unknown Artist" as artist

[Magikh42]

Tried witth Spotify using Multi-Scrobbler and in the webadmin Exemple track: Unknown Artist - Who Got Me Workaround: In the webadmin replace "Unknown Artist" by another name like "(Unknown Artist)"

It's not well documented but in your settings.ini you should be able to set invalid_artists which should prevent maloja from using the default values that prevent Unknown Artist from being scrobbled.

invalid_artists = ["DefinitelyNotARealArtist","Spotify"]

Thanks it solve the issue Shouldn't the default be an empty list, because Spotify uses "Unkown Artist" for tracks without credited artists

IMO Maloja should tolerate scrobbles of songs with no known artist. Currently, if all song artists (those extracted from the artist_name parameter) are also in the invalid_artists list, it returns a 500 internal error. Navidrome (for example) will then get stuck and keep sending the broken scrobble.

The easy workaround is to remove the offending unknown artist text from invalid_artists, as FoxxMD said.
