Error:
title:62 - Title is a required field for adding items
Resolution:
This error can be typically returned when a bulk file with action=add has been submitted for processing, but there weren't any values in the title / ebaytitle header or that header wasn't included in the file and since it is one of the required fields for listing on all marketplaces, a value needs to be added. For more information about all of the required and recommended fields please see this guide.
