I am also looking to use the API Gateway 9.2 as an OAuth2 Authorization Server with the OTK 3.6. This is all done using a single container with the caapmi/gateway 9.2.00-7070_CR01 Docker image. I went through all the steps as specified on the OTK Wiki as well as this handy Youtube video; however, when I use the OAuth2 test client with Authorization code, I got an "oob" scope back upon the handshake. Upon granting access, I don't get back an access token.
Any debugging tips or if I messed up somewhere?
