You have SCOPE=None?

The access token must have the user-read-currently-playing and/or user-read-playback-state scope authorized in order to read information.

Correct. And Duh! It needs to be user-read-currently-playing.

I'm a little unclear on where to look for how to handle tokens. Would the app, potentially store (and when necessary replace) different tokens for different tasks?

Does the request only accept a single scope at a time?

This is interesting. When I run the example with a the main scope as user-read-currently-playing, it returns an Address Already in Use error and look, it seems to, indeed, be running twice on the same port:

$ ps -fA | grep python
  501 19517 15945   0  3:25PM ttys025    0:00.25 /usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python -m flask run --port=8080
  501 19518 19517   0  3:25PM ttys025    0:00.28 /usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python -m flask run --port=8080

Update

But that's not what's causing the error, as it runs two threads with a scope of None as well, which doesn't give the same error.

@MikeiLL commented on GitHub (Jul 7, 2020):

The cause of this problem is that there needs to be, if I am understanding correctly, a new spotipy.oauth2.SpotifyOAuth for each new scope.

I am seeing that multiple scopes is possible, but I'm not sure what that would look like.

In my case, so far, I only need a single scope, so once I logged out, I was able to instantiate the single spotipy.oauth2.SpotifyOAuth with the required scope.

I wonder if the demo, app.py, should be one that includes a specific scope, for example:

# code omitted for now
auth_manager = spotipy.oauth2.SpotifyOAuth(scope='user-read-currently-playing', 
									show_dialog=True, 
									cache_path=CACHE)

# more code omitted

@app.route('/currently_playing')
def current_playing_track():
	if not session.get('token_info'):
		return redirect('/currently_playing')
	else:
		cur_track = spotify.current_user_playing_track()
		if not cur_track:
			return f'Seems there is no currently playing track.'
		else:
			return cur_track

If that seems useful, I'll be happy to send a pr.

Answered the multiple scopes issue here https://github.com/plamere/spotipy/issues/537 – I don't think it needs a different spotipy.oauth2.SpotifyOAuth for each scope

Answered to you about the "missing cache or username" problem here https://github.com/plamere/spotipy/pull/529#issuecomment-657185855 – you were right, something is wrong. For that problem we can use this issue https://github.com/plamere/spotipy/issues/533

I agree the script could show an example that uses scopes (just one or multiple), please do open a PR if you get this working!

@MikeiLL do you still have the "permissions missing" issue or can we close the current issue and focus on https://github.com/plamere/spotipy/issues/537 only?

Closing this one, as the problem was setting scope to None, when making requests that require user-read-currently-playing (i think there's a second scope that also grants permissions for current_user_playing_track.)
