Hi there,
Thanks for reaching out to the Google Ads API Forum.
I can see that the error you have encountered is an unauthorized_client error. Could you confirm if you generated refresh token by following this guide for the Python client library? It would be good to check this configuration, in order to narrow down the issue.
Once you have followed above, you may retry your request and see if it works without any error. If still an issue, then you may privately send us complete logs in the format of the request and response logs along with request-id as seen in their respective links. To capture these full logs, you may ensure you have followed this logging guide implemented on your end.
