I've been trying to set up GAM version 3.21. Trying to run 'gam info domain' gives me a whole list of options, I don't get prompted for the primary google domain as in the first time setup instructions.
I then select option 21 to continue and it falls out of GAM telling me there is a problem with the jsn file.
I found information the said I needed to create our client-secrets.jsn file - so I followed the instructions to create this and then renamed it copying it into my c:\GAM folder.
I ran 'gam info domain' again and this time selecting option 21 to continue it opened a web browser and reported error 401: invalid client
There is a suggestion in the jsn file instructions to run 'gam oauth info' to check the client ID however I get the same result trying to run this command as well.
Can anyone help with this?
