Issue:

We are facing an issue with the Shopify integration where return orders created in Shopify are not being reflected correctly in the system.

Current Flow:
When an order is created and fulfilled in Shopify, the system correctly creates the corresponding Sales Order (SO) and Delivery Note (DN) in ERPNext. However, when the order is returned and restocked in Shopify, the Sales Return is not created in ERPNext.

Steps to Reproduce:

1. Create an order in Shopify.
2. Fulfill the Shopify order.
3. Create a return for the order in Shopify and restock the products.
4. Observe that the Sales Order and Delivery Note are created for the Shopify order, but the Sales Return is not created in ERPNext.
