For example when connecting to a customer's account, i recieve this:
Request with ID 'hjCy3cXHtU4xSwgGNP0GsQ' has failed.
Google Ads failure details:
authorization_error: The customer (or login customer) isn't in Google Ads. It belongs to another ads system.
However it immediately exits the script and i have no recourse for catching it, or handling any data or errors.
