Re: [keycloak-user] Keycloak Admin Client, create user, error 500, Internal Server Error

I'm using Keycloak 2.5.1 Final, Keycloak Admin Client 2.5.1 Final, Resteasy Client 3.1.0 Final and Resteasy Jacksom2 Provider 3.1.0 Final. I'm using the code above to test create an user using the Admin Client. When the application run the create method, the response returns error 500, Internal Server Error with the trace above on Undertown server. I'm missing something? Keycloak kc = KeycloakBuilder.builder() .serverUrl("https://IP:8443/auth/realms/sgp/protocol/openid-connect/auth") .realm("testrealm") .username(adminUser) .password(adminPassword) .clientId("admin-cli") .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build()) .build(); userRep = new UserRepresentation(); userRep.setFirstName("John"); userRep.setLastName("Doe"); userRep.setEmail("john.doe(a)test.com"); userRep.setEnable(Boolean.TRUE); Response response = kc.realm(realmId).users().create(userRep); 17:19:58,337 ERROR
