Webhook: Create Order is showing "Unknown" for product_type field

When I receive a order/create webhook payload, that payload has the product_type field in the line_items object array, but product_type is showing “Unknown” instead of the type that is assigned to the product (“Tops” for what is actually assigned to that product).

I have the Product Type defined on the product in the Shopify store of “Tops”, but when it is ordered, the type simply says “Unknown” in the payload. I would expect this value to be “Tops” instead.

This is for API version 2025-10.
