Getting error 404 for /service-worker.js since 1.0.0-next.207

[kevinrenskers]

Describe the bug

When I updated from 203 to 210 I noticed that I was getting the following errors:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (service-worker.js, line 0)
[Error] Unhandled Promise Rejection: TypeError: Script http://localhost:3000/service-worker.js load failed

This happens with npm run preview and on the actual production site, so I've downgraded back to 206 for now.

Reproduction

https://github.com/kevinrenskers/sw-repro

Basically it's just the standard demo app, with adapter-node. Run npm run build and npm run preview, open the website, and look at the console.

Workaround: rm -rf build .svelte-kit && touch src/service-worker.js && npm run build && npm run preview

[yuanchuan]

Try to update svelte.config.js

kit: {
  /* ... */

  serviceWorker: {
    register: false,
  }

}

Thanks, that helps!

(Ignore the pre-edit text, I put the code in the wrong place)

@Rich-Harris
Why do we need to do this all the time!😐

Try to update svelte.config.js

kit: {
  /* ... */

  serviceWorker: {
    register: false,
  }

}

Doesn't work

I see, the error that I'm getting is deferent than this one, and this issue created at 2021, not 2022 :)

This is my error message:

@smithliam i'm getting the same error on this end. anyone @here have some ideas?

[sourcegr]

@smithliam @oneezy

go to chrome://serviceworker-internals/

and click unregister at the service worker that is bound to the port you are running node (mine was 3000)

Do you guys know why this happened? I fix it by using @sourcegr 's solution, but would like to know the cause.
