I set this PR as ready for review since url is defined as nullable in YouTube.js (even without the changes from my YouTube.js PR) so this should be merged even if we can't find any issues at this moment

What specific screen(s) can be viewed to run the changed code? I would like to just run the code once

AFAIK the YouTube music channel is the only channel that needs this. I'll close this PR for now and will reopen it if necessary
