[keycloak-user] KeycloakSession users() returns UserRepresentation with no name after REGISTER event

Hi, I'm using an EventListenerProvider to catch user registration events (when the user registers via Keycloak's Registration Form) and send the registered user's details to an outside system. Here's the relevant code: public class LocoinsEventListenerProvider implements EventListenerProvider { private final KeycloakSession session; // provided in constructor @Override public void onEvent(Event evt) { if (evt.getType() == EventType.REGISTER && Objects.equals(evt.getRealmId(), this.realm)) { final String userId = evt.getUserId(); final RealmModel realm = session.realms().getRealm(evt.getRealmId()); final UserModel user = session.users().getUserById(userId, realm); log.info("Customer registered, notifying application: id = {}, name = {} {}, email = {}", userId, user.getFirstName(), user.getLastName(), user.getEmail()); } } } The problem is that user.getFirstName(), user.getLastName() are both null (but user.getEmail() holds the correct value). If I check the Keycloak database directly after this (table USER_ENTITY), FIRST_NAME and LAST_NAME are both there. Any ideas why this might be? How should I get what the first and last name entered by the users? Thanks! P.S. If I create the user via the Keycloak REST API client and then catch the corresponding Admin event (I don't get a REGISTER event in this case), the UserRepresentation obtained in the same way as above holds all the data (first, last name etc.): final UserRepresentation user = new UserRepresentation(); user.setUsername(email); user.setEmail(email); user.setFirstName(name); kc.realm(*"MyRealm"*).users().create(user);
