Hi Everyone,

I am trying to create a new contact record when the new user is created.

This trigger code gives this error.

trigger NewContactOnUser on User (after insert) {
    List<Contact> contacts = new List<Contact>();
    for (User u: trigger.new){
        Contact c = new Contact();
        c.FirstName = u.FirstName;
        c.LastName = u.LastName;
        contacts.add(c);       
    }
    insert contacts;

Error is this..

Error: Invalid Data.
