For some reason I'm not able to add certain users(emails) to google groups using the Cloud Identity API. More specifically, if the email is from a very well known domain, like Gmail, I'm always able to add a user, but when the email is from a not so well known domain, the API returns an error:
'Error(2028): Permission denied for resource groups/ (or it may not exist).'
Is there a way to workaround this issue?
I'm using Python in my project.
