Hi, This error normally happens if you missed something in the configuration of OAuth2 credentials or refresh token. Could you please confirm if you followed this guide <https://developers.google.com/adwords/api/docs/guides/authentication> to generate your credentials and which app type have you configured? Also, please make sure that when generating the refresh token for a test account, you're logged in as a user of the test account and not the production account.
