Failed to Load Value at Index Exception

When you are doing any VO extension following error is common.
The reason is you have created the custom VO based on a verion and migrated to a instance which is of higher version and the product team has changed the VO definition ( addition of extra attribute).in the later instance.
The solution is to recreate the VO based on the version you are going to upload.
