I am using "gam user xyz1 sendas group1 'groupname' " but am getting an error stating "Add Failed: Precondition check failed".
It seems to only be happening with two particular users and this particular group. I can add a sendas to other groups. For testing purposes, I did the below.
When I try giving my account sendas access to the group, it works. When I try adding the two users to a test group, it works. When I try adding them to the group in question, I get the preconditon error.
What are some preconditions GAM might be looking for when running this? Thank you
