Error Code 13013
While this error could be referring to an issue with the SKU on Amazon's end, it is also possible that, locally, the condition mapping isn't properly set up in the product type. This SKU does not exist in your Amazon inventory so we could not process this record. To correct this error for future feeds, add the SKU to your Amazon account.
You must resend the create feed to Amazon because the SKU is not in the Amazon catalog. You may have sent a missing or wrong feed to Amazon so try to send product data updates to the channel and sync the channel from the top left corner.
