During authentication, you receive this error message:
Status 400: Additional permissions are required. Please ensure you select all permission checkboxes and try again.
- The required scopes were not selected or enabled during the authentication process
- (Google account) The user hit 'Cancel' instead of 'Allow' during the Google permissions page
- As a test, try re-authenticating with all scopes. If this passes but the user doesn't want all scopes enabled, re-authenticate again with only the required scopes.
- Ask the user to re-authenticate, and select 'Allow' during the Google permissions page
