Note, have note changed the code for example q01 and am simply trying to test it as is on paper trading when this error is being thrown.

Only brokerage accounts have access to the premium Polygon data service. For now, we are providing this data to all brokerage accounts - i.e., those accounts that have the ability to live trade - free of charge, but in the future, that data is likely to move to only accounts that subscribe to that data service. The expectation is that most people will be using Alpaca’s data API. I’m working on fixing up our documented examples to make things like this clearer. I’ll keep this issue open for now as a reminder to clean up (i.e. change the API used in) q01, but in the meantime, you can either register your paper trading account to get live trading permissions or change the code yourself to use the Alpaca data API instead of the Polygon one.
