rest-module not working - 404 on hello endpoint

[kikkauz]

Hello

Willing to learn about extensions in the keycloak-X, I'm following your great resources.
However I'm not able to make the rest extension work. It is deployed, I can see it in the provider info as deployed, but when I try to curl the /hello endpoint (e.g. curl http://localhost:8080/auth/realms/master/my-rest-resource/hello), I get a 404
Do you have any hint to help me understand the issue?

Thanks!

If you use a new fresh Keycloak >= v17, then probably you want to remote the auth path part from your URL.

Thanks for the quick reply. While I still get a 404, the situation has somehow improved as I moved from a
{"error":"RESTEASY003210: Could not find resource for full path: http://localhost:8080/auth/realms/master/my-rest-resource/hello"}
to
{"error":"HTTP 404 Not Found"}
And also a better stacktrace to follow:
Error response 404: javax.ws.rs.NotFoundException: HTTP 404 Not Found

I will dig into it and let you know if I discover anything

Problem solved. It was in fact the "auth" to be removed. Thanks!
