I'm currently running 4.12.4-1-ARCH

I get this as well - seems like it can't load the 'general library'.
It does however work fine when you want to locate a song in the media library eg. using '~' bind in ncmpcpp. It will then locate the artist and song in the media library.

My temporary fix to deal with this is just to reduce the timeout to something bearable, and only use media library through eg. '~' and instead rely on searches.

In .config/mopidy/mopidy.conf

[spotify]
timeout = 2

@ecly
I just unbound the keymap to show_music_library to whatever the default keymap set to '1' is.

[ecly]

@hshin23 yeah, that's another workaround if you don't want to use the library altogether. I find it quite nice for browing songs by an artist of a song using '~'. I guess you can still use that feature without the musc library bind though, you'll just have to query the song every time. Either way, would be cool if the media library as a whole could be implemented in a way that doesn't cause hang when you visit it the first time without any context.

[colonelk1]

Same issue. Does anyone have suggestions how to get the local library up and running then?

[ecly]

@colonelk1 I think it's a matter of implementing it in mopidy-spotify, unless you use it indirectly, by eg. going to a specific artist using '~' in ncmpcpp

[valerius21]

same error still exists for me too. It makes the general library useless.

[matrss]

same here. the mentioned '~' workaround doesn't even work for me.

[marcosmoura]

Same here. ncmpcpp freezes.

This looks like it failed to load a playlist and will have been fixed by f52babd
