invalid_grantAn agent uses a Google OAuth client whose consent screen has publishing status Testing.
It works for a week, then token refresh fails with invalid_grant.
For an external user type in Testing status, Google issues refresh tokens that expire in 7 days (unless only basic profile scopes are requested).
Move the consent screen to production, or plan for a re-authorization every 7 days.
# check publishing status of the OAuth consent screen: Testing vs In production
After moving to production and re-authorizing, the new refresh token keeps working beyond 7 days.
