Problem is here –
Uncaught server error: org.jboss.resteasy.spi.InternalServerErrorException: RESTEASY003815: Subresource for target class has no jax-rs annotations.: com.mtsmda.endpoint.CustomEndpointResource

org.jboss.resteasy.resteasy_jaxrs.i18n.Messages_$bundle#subresourceHasNoJaxRsAnnotations$str

problem here –
if (!GetRestful.isSubResourceClass(clazz))
{
String msg = Messages.MESSAGES.subresourceHasNoJaxRsAnnotations(clazz.getName());
throw new InternalServerErrorException(msg);
}

org.jboss.resteasy.util.GetRestful#isSubResourceClass
in class level shouble be – javax.ws.rs.Path

now in my class – i do not set this annotation(I did as here – https://github.com/dasniko/keycloak-extensions-demo/blob/main/rest-endpoint/src/main/java/dasniko/keycloak/resource/MyResourceProvider.java)

If i right understand I should set in class level that – javax.ws.rs.Path annotation

Can you please give me your expert advice? thanks!
