500 Internal Server error

[stanleesocca]

Hi Thanks for this amazing book. I've been studying the codes detailed in this book and trying it out for myself. However, I have an issue that I can't figure how to resolve for Chapter 2. I still get stuck in "Authorizing our application with authorization code flow" section whenever I type python spotify_auth.py it produce a callback error with:

Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

In the browser (microsoft edge). In the terminal I get

Traceback (most recent call last):

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)```

I'm not sure what to make of this and how to bypass this one. Any help?

Thanks Daniel. Sorry for my late response. Still haven't had any luck with that part. Hope we get a solution soon.
