App extension js file keeps being cancelled by service worker

Topic summary

Extension JavaScript for a customer-ui component on the order status page is consistently being canceled by a service worker, yet loading the same JS file directly in the browser works. This suggests the request is intercepted during page load but not when accessed standalone.

Evidence: an attached browser DevTools Network screenshot shows the JS request with a “canceled” status. (Images are central to understanding the network behavior.)

Context: a service worker is a browser background script that can intercept and cache network requests; misconfiguration or caching rules can cause requests to be canceled on specific pages.

Latest update: a participant asked whether the issue is still occurring, indicating a check-in but no new technical details.

Outcome/status: no fix or root cause identified; no configuration changes or logs shared. The thread remains open and awaits the original poster’s follow-up.

Hi, I am developing a customer-ui extension for the order status page, But the extension js request keeps being cancelled, when i manually visit that js url, it show up fine. Why does that happen?
