Coupons Page Not Loading Any Content

Describe the bug

To Reproduce
Steps to reproduce the behavior:

Log in to the admin dashboard

Navigate to the Coupons page

Observe that the page does not load any content

Expected behavior
The Coupons page should load and display all existing coupons, along with options to add, edit, or delete them.

OS: Windows 11

Browser: Chrome

Additional context
This issue blocks the ability to view or manage promotional coupons, potentially affecting ongoing marketing campaigns or discount features on the platform.

Start by reproducing the issue in the admin dashboard by opening the Coupons page in Chrome, then inspect the page and its network requests to identify why content remains blank or loading. Done means existing coupons and the add, edit, and delete options render successfully.
