I am receiving product_listings/update webhooks` with broken images. For example
```
“X-Shopify-Event-Id”: “a000bd05-7685-47df-b797-399cb819e128”,
“X-Shopify-Triggered-At”: “2025-11-12T19:09:14.630063088Z”
```
The event contains an array of images but all `src` field values end in 404s.
Why is this happening?
