Error Getting Attachments for a Purchase Order

I’m following the example in Lesson 3.1 of the I310 training course.  But instead of retrieving attachments of a Stock Item, I want the attachments of a Purchase Order.  In Postman, I’m performing a GET to:

https://localhost/PhoneRepairShop/entity/Default/20.200.001/PurchaseOrder/000001?$select=OrderNbr,files&$expand=files

 

The response is: Operation is not valid due to the current state of the object.

 

This happens for both open and closed purchase orders.   Am I missing something?

 

There are two key fields for purchase order.

Type and OrderNbr which one must specify in the uri.  So, it should be:

 

https://localhost/PhoneRepairShop/entity/Default/20.200.001/PurchaseOrder/Normal|000001?$select=OrderNbr,files&$expand=files

 

assuming its type normal purchase order.

 

Thanks
