I am getting the following oxd errors when I try to register a client. Is there something wrong with my Gluu server setup? I can register successfully with a Gluu 3.0.2 server and oxd 3.0.1. Also, I can manually create a client with Gluu 3.1.0 and use mod_auth_openidc. Do I need to specify the client ID and secret in my registration request?
