[keycloak-user] Change 403 Message

Hello, is there a way to change the message displayed on the 403 json response? If i try to to access a resource that i don't have the permissions for, i get the following json response: { "timestamp": "2019-10-07T13:31:47.274+0000", "status": 403, "error": "Forbidden", "message": "Access to the requested resource has been denied", "path": "/api/" } but what i want is: { "timestamp": "2019-10-07T13:31:47.274+0000", "status": 403, "error": "Forbidden", "message": "To access these resources mail to ....", "path": "/v1/" } I know i could do a redirect via policy-enforcer, but i have to avoid a redirect. Greetings, Florian
