Hello I hope you can help.
When I want to create my user I do follows

Keycloak keycloak = Keycloak.getInstance (getURL (), "MyRealm", "myUser", "myPassword" clientID);
UserRepresentation userRep = new UserRepresentation ();
userRep.setUsername ("testUser");
CredentialRepresentation CredentialRepresentation credentials = new ();
      credentials.setType ("password");
      credentials.setValue ("t");
      List <CredentialRepresentation> list = new ArrayList ();
      
      list.add (credentials);
      
      userRep.setCredentials (list);
        userRep.setEnabled (true);
        userRep.setEmail ("myMail@outlook.com");
        userRep.setEmailVerified (false);
        userRep.setFirstName ("Javier");
        userRep.setLastName ("Javi");
        
        Map map = new HashMap ();
        userRep.setAttributes (map);
        
        UsersResource users = keycloak.realm ("MyRealm") users ().;
        
        Response response = users.create (userRep);





first responds with code 200

- 18:14:09 DEBUG org.apache.http.impl.conn.DefaultClientConnection:254
Receiving response: HTTP/1.1 200 OK




but at the end responds with a 500 error and I don't know why :(:
