api returning empty sku for certain line_items

[jamestan]

using api, we called:

https://hidden:hiden@kbright-sg.myshopify.com/admin/orders.json to retrieve orders 

and we found many orders that return line_items.sku empty string.

but other orders works fine. when we check the sku in the product page, its the sku exists

any reason for this to happen?

Hi @jamestan,

An order's line item is a snapshot of the variant as it was at the time of purchase. If there's no SKU value on a line item, it meant the associated variant had no SKU at the time of purchase.

Hope that helps!
