Hi Andrew, The error message you specified appears to indicate that you have not fully migrated to the latest AdWords API version and the new client library version, rather being an OAuth2 credentials issue. This being said, you may refer to our migration guide <https://developers.google.com/adwords/api/docs/guides/migration/v201710> to get familiar with the changes in the different services and reports included in the latest AdWords API version and apply further changes in your code if necessary.
If you are still encountering other issues that you suspect are related to your OAuth2 credentials, you may send to me privately (via the *Reply privately to author* option) the generated SOAP request and response logs so I can further investigate.
