What happended?

The admin dashboard crashes with a TypeError: Cannot read properties of undefined (reading 'reduce') when attempting to view a customer detail page where the customer has orders containing product variants that have been soft-deleted.

To Reproduce

1. Create a customer and place an order with a product variant
2. Delete the product variant (soft delete)
3. Navigate to the customer detail page in admin (/admin/customers/{customer_id})
4. The page crashes with the error

Expected behavior

The customer detail page should load successfully, displaying orders even if the associated product variants have been deleted. The order history should remain viewable since the order line items store the product/variant information at time of purchase.

Actual behavior

Actual behavior

The customer detail page crashes immediately upon loading. React Router catches the error and displays an error boundary. The browser console shows:

TypeError: Cannot read properties of undefined (reading 'reduce') at cell (chunk-EHU67PIM-BMUMX0qB.js:1:3101) at Jf (index-GickE7Mp.js:176:383) at sTe (index-GickE7Mp.js:192:9930) at XF (index-GickE7Mp.js:194:11975) at _D (index-GickE7Mp.js:211:2160) at IH (index-GickE7Mp.js:207:22381) at jSe (index-GickE7Mp.js:207:21958) at t0 (index-GickE7Mp.js:207:21708) at SD (index-GickE7Mp.js:207:18203) at EH (index-GickE7Mp.js:207:19594)
