Shopify Sales Invoice creation

I am having an issue with the Shopify integration where Shopify Log entries are being created, but always with an error:
Could not find Row #1: Stock UOM: NYXL1046

Note that the reference to NYXL1046 corresponds to the ERPNext Item Code/Shopify SKU.
In ERPNext the Item is set with a default UOM of “Each”.
There is no UOM field in Shopify Product to set a UOM that corresponds to “Each”.

It seems that the code should be using the default UOM from the Item record while creating an Order/Invoice, but it is not.

Any insight into how to resolve?

Here’s the full error
