Problem saving MyContactList.cmp.
Field_Integrity_Exception: Failed to save MyContactList.cmp: Invalid definition for null:MyContactListComponent: null: Source

public class MyContactListController {
@AuraEnabled
public static List<Contact> getContacts(Id recordId) {
   return [Select Id, FirstName, LastName, Email, Phone From Contact Where AccountId = :recordId];
}
