Error serving a Unity3D webgl project after I installed flutter on my machine

[paulorenanmelo]

I'm getting ERROR: GET /flutter_service_worker.js?v=2538856064 [404: does not exist], even though flutter is not running anywhere - as far as I'm aware.

Sorry but I'd need a repo to tell you what's wrong. It's possible some other app you served locally is using a service worker in which case you might be able to fix it by going into your browser's devtools and deleting the service worker.

In Chrome I seem to be able to go to

chrome://serviceworker-internals/?devtools and then if there is one registered for localhost, unregister it.

Sure. Here it is.
Cube.zip
I don't think it's relevant in this case, because there's nothing related to google flutter in this project. Pretty much anything I try to serve will throw this error:

And you're probably right, it might have been a google flutter hello world or something that I ran once on the browser and it persisted.
