Note: it try to use xhr2-cookies as a fallback, but it is a Node module, not work on Worker either. We've patched xhr2-cookies to return empty.

Could you please point to a minimal repository or make new one fast on codesandbox.io or similar cloud IDE, so we can help you more? Thanks,

I tried to reproduce this and found XMLHttpRequest is defined in a Worker, but not in a Service Worker.

Our app runs in a service worker (Chrome extension), where XMLHttpRequest is undefined.

The code use typeof XMLHttpRequest === 'undefined' to detect if the runtime is NodeJS, which is incorrect on our platform. Is there anything else you can use? For example, typeof self === 'undefined'.

I guess this is fixed by #5085?
