I can add some additional checking to be sure the response has been parsed into a JSON object (dict) and thereby avoid the TypeError and early program termination.

The question is why didn't the response get parsed into JSON? From code inspection, the most likely reason would be that the response from the service did not include a Content-Type header with a value that included "application/json".
