Errors reported on debug port

[dogastus]

I have the app running and displaying the Spotify logo on the OLed display. But I can't get it to show any Spotify playback info.

I get this on the debug port when I start it up:

Then, if I press one of the buttons, I get this:

Try to obtain a new authorization code. The code is valid for a few minutes only, so when you get it, just copy-paste it into device right away. Also, do not post the code or the string generated from it (Authorization: Basic ...) publicly.

I think I must have not been careful enough with my cut and pasting somewhere. It's working now. Thank you for the great app.
