Recently, I encountered an issue related to fulfillment creation:
My app cannot fulfill a virtual product in a specific order after it has been processed by another app, as shown in the image below:
In this image, you can see that the “mystery gift” is also a virtual product. After it was processed by this other app, I found that my app could no longer access any fulfillment orders for the virtual product “Shipping protection.”, the corresponding structure is empty.
However, when my app accesses other orders with the same product, “Shipping protection,” that haven’t been processed by this other app, everything works fine.
My question is: Why does this happen, and how can I resolve it?(Graphal API) Thank you.
