I'm try to create an oauth client with client-credentials type, but I receive the message "API Error: 400 - Client roles must not exceed the creating user".
It's the same problem to this topic
and I don't understand how @kellcomet resolved the issue. Any idea?
Your user can't grant roles you don't have to a client you're creating/editing. Be sure your user has all of the roles that are being set on the client.
