Spotipy hangs, no errors

[deramirez1]

Describe the bug
There is an issue with logging and exception handling.

Your code
To recreate this I just used one of the examples from the documents:

Simply passing in some valid credentials and seeing if I can get albums from an artist. I ran this in a loop 10-20 times in a short period of time, with my app in developer mode.

After much digging, I was able to track the problem down by stepping through some functions until I got to the actual GET HTTP request. I looked at the payload, extracted the token, and checked if it was valid. It was not.

I'm in developer mode, without a quota extension. I believe the issue is actually stemming from this rate limit. I've waited a couple days, the problem resolved itself but then after a few calls it came back. Is there an error with the callback that's not returning the 429 error expected here?

Expected behavior
I expected to get a list of albums from this artist but that didn't happen.

Output
Probably the most frustrating of all is that it just hangs. There's no callback saying the token is invalid, or a rate limit has been exceeded, it just spins and spins. The warning expected from Spotify would actually be very helpful. It'll say how long we need to wait until we should execute another HTTP request.

Environment:

• OS: Windows 10
• Python version: 3.8.3
• spotipy version: 2.20
• your IDE: originally Jupyter Notebook, but then VS Code has the same problem

Update: i was previously using SpotifyOAuth so i tried SpotifyClientCredentials and it ended up working. didn't change anything else. same notebook as above.

Check if you are not getting a 429 error (too many requests per Spotify client ID).
