Spotify authentication doesn't work

[benthillerkus]

Hey, not sure if I'm configuring stuff correctly, but in the Spotify app, I've set the redirect URL to localhost:8080.

When I run spotify_to_ytmusic commands that require Spotify auth, the browser opens first a Spotify login page, and after signing in redirects to a page that says INVALID_CLIENT: Invalid redirect URI.
That page has a URL that looks like this:

https://accounts.spotify.com/authorize?scope=user-library-read&response_type=code&flow_ctx={{a uuid}}%3A{{a unix timestamp}}&redirect_uri=http%3A%2F%2Flocalhost&client_id={{the client id}}

Pasting that URL back into spotify_to_ytmusic does not work:

Could not get Spotify playlist. Please check the playlist link.
 Error: SpotifyOauthError('error: invalid_request, error_description: code must be supplied')

You need to set the redirect URI in your app settings in the spotify developer console
