Error:
title:62 - Title is a required field for adding items
Reason for Error:
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 your bulk file. This means you are trying to add a new product in the system and at the same time attempting to publish it to your eBay store.
Resolution
Since the title field is one of the required fields for creating the product in SureDone & listing on eBay (+ all marketplaces), a value for this needs to be added. You can either add the product in a bulk file again using the title field and upload the file OR you can simply add the new product in the UI.
For more information about all of the required and recommended fields please see this guide.
