"Orders" Page Displays Error Instead of Order List

Describe the bug
On the admin dashboard, the "Orders" page displays the following error instead of the order list:
Error: Cannot return null for non-nullable field User.name.
This prevents administrators from viewing and managing orders.

To Reproduce
Steps to reproduce the behavior:

Log in to the admin dashboard.
Navigate to the "Orders" page.
Observe the error message: "Error: Cannot return null for non-nullable field User.name."
Expected behavior
The orders should be displayed normally. If a user name is missing, the system should handle it gracefully instead of throwing an error that blocks the entire page.

Additional context
This appears to be a GraphQL issue where a null value is returned for a required field. The system should allow for null values or provide fallback handling to prevent the UI from breaking.

Start by reproducing the error on the admin dashboard's Orders page, then trace the GraphQL User.name field and the order-list request. Determine where the missing user name is returned and verify the Orders page renders and remains usable when that value is absent.
