I have a web worker that is making fetch calls and then running some wasm code (so that it doesn''t block the main thread).

Everything works great. But when I run pnpm build && pnpm start the worker doesn't work.

If I comment out all the fetch calls in the web worker , then I see console.logs in the web worker's onmessage handler but if I leave the fetch calls in there, then I don't see the console log at all.

Does anyone know what's going on?

Do I need to add something to my next config
