Load service worker entry point from nested folder with MV3

[Clément Vidal]

Hello, 

Is there some kind of limitations with manifest v3 extension that would prevent me to use a file stored inside a nested folder as a service worker entry point ?

Exemple:

"background": {

"service_worker": "Webpack/Background.js"

} 

When doing so, chrome output the following error: `Service worker registration failed`

If i use the exact same file, but this time stored at the root of the extension bundle, everything works fine.

Do you have any clues ?

Thanks,

Clément

I guess it is based on the same principle of service workers. They control the path (and sub-paths) they reside in.

It seems to be working as intended to me.

This is what I could find after a short search -

https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API/Using_Service_Workers

"The max scope for a service worker is the location of the worker."

PhistucK is on the money. The service worker file must live in the extension's root directory. I opened a bug for this (crbug.com/1136582) hoping it would be an easy fix, but it appears to be a more complicated issue than I originally thought.

Thanks for your quick answer guys, i'll take a look at this service worker scope notion.

Cheers

I believe the scope property can only narrow the scope, not widen it.
