We have a partner firm that kept their email domain when we aqzquired them. We integrated their mail domain into our Gmail instance. We have some applications that will only allow access to users with our domain email address. I have tried to extend the google email alias attribute by constructing an attribute from their user attributes (firtName.lastName@parentemaildomain.com) via regex and calling it SecondEmail in Okta, then mapping that SecondEmail to google emailAlias. When I try this in my dev instance, I get an error "Invalid value data type for property 'emailAliases'"
How do I get this working?

I think we might need to see the expressions you're using to know whether you're producing data of the wrong type.
Or, and this is a guess: is your domain email address verified with Google? According to this and this, "the API requires the domain's ownership be confirmed before the user alias can be created".
Tim, the domain is verified. I have been working on it with our Google admin.
in the meantime, I opened a case so I can get a session with support.
Thanks
