Cannot browse Youtube within Mopidy library

[mgoltzsche]

When I browse Youtube in the Mopidy library, the two available directories "My Youtube artists" and "My Youtube playlists" are empty and errors are logged.

Browsing "My Youtube artists" fails with the following errors being logged:

Browsing "My Youtube playlists" fails with the following error being logged:

I enabled musicapi_enabled, configured my channel_id and the musicapi_cookiefile as well as youtube_api_key for which I also enabled api_enabled.

I am using

• mopidy-youtube 3.7
• ytmusicapi 1.2.1

I would expect to see artists and playlists and no errors being logged.
Am I using mopidy-youtube the wrong way? Does it work for you?

This is not really a blocker since the Mopidy search works with Youtube but it would be nice to have that fixed - ideally I'd want to browse tracks I liked on Youtube.

(As opposed to the other issue I just created, this is not a new problem that appeared after a recent Youtube change but always existed in my setup.)

Also, the mopidy-youtube readme explains that musicapi_browser_authentication_file should be configured to make the ytmusicapi authenticate properly but apparently mopidy-youtube does not support such a configuration key. I guess it generates the browser.json for the ytmusicapi from a given cookies.txt file?

[mgoltzsche]

I thought maybe the ytmusicapi version I used is too new since there was a breaking change in its version 0.23.0.
Thus, I tried using version 0.22.0 (and 0.23.0) which logged a slightly different error when trying to browse "My Youtube playlists" but resulted in the same broken behaviour otherwise:

@mgoltzsche Just ran into this myself. It's because 3.7 was released in May but the fix was merged in July. Put this in your requriements.txt file instead, and make sure to uninstall the existing version, if any, first.

git+https://github.com/natumbri/mopidy-youtube.git@develop#egg=Mopidy-YouTube

@mgoltzsche also musicapi_cookie is now musicapi_cookiefile and it looks like the musicapi_browser_authentication_file doesn't support using env vars

[mgoltzsche]

@daredoes Thanks for pointing that out! Unfortunately, when using the latest commit on the develop branch and letting musicapi_browser_authentication_file point to a browser.json file (generated using ytmusicapi) it also doesn't list Youtube contents within the Mopidy library but logs the same error: Server returned HTTP 500: Internal Server Error.
Does it work for you? Maybe this time the error is also due to the last breaking Youtube change, given that I fixed my configuration and used the latest commit? Or is the feature still in the making?
