Resolution:
This error seems to be similar to the "No item found with a given SKU" error on Walmart or "Can't find merchant SKU" on Jet. It appears on a new listing when the inventory feed is accepted before Amazon processes (and creates) the SKU itself. This will resolve itself once Amazon creates the SKU; however, we have seen it take up to 12 hours to do so.
