Hi everyone,

I am testing an OAuth2 setup on InterSystems IRIS 2026.1 (Community Edition), based on a workshop with separate Auth Server and Resource Server instances (https://community.intersystems.com/post/learn-how-use-oauth2-openid-con…).

On the Resource Server, when I try to use Dynamic Registration and Save in OAuth 2.0 Client Configuration, I get this error:

ERROR #8881: Dynamic client registration endpoint is not configured.

What I already checked:

1. OAuth2 Server configuration exists on the Auth Server.
2. Issuer endpoint is set and reachable.
