Shopify only accepts a few specific values otherwise will return an error. Most likely what happened was that one of your columns had values outside the options that Shopify allows. For instance, in the finances column Shopify will only allow: “pending” (The finances are pending), “authorized” (The finances have been authorized), “partially_paid” (The finances have been partially paid), “paid” (The finances have been paid. This is the default value.), “partially_refunded” (The finances have been partially refunded), “refunded” (The finances have been refunded), “voided” (The finances have been voided). Any other values entered in this column will cause an error and Shopify will not accept the orders.
