How do I fix "Insert sku outer id relation failed, outerId already exists" errors from Lazada?

This error happens when the Seller SKU you are using is not unique. Every variant on Lazada must use a unique Seller SKU and if you are already using a SKU for an existing variant on Lazada you cannot use the same on a new Variant. To fix this please read: How do I fix "Seller sku id is duplicate" errors when I try to add a new product to Lazada?
