Exported HTML 5 game works fine on Firefox but not on Chrome (Windows 10)

workermain.js:1 Refused to execute script from 'http://localhost:8000/scripts/c3runtime.js' because its MIME type ('text/plain') is not executable. a workermain.js:1 workermain.js:1 [C3 runtime] Failed to load all engine scripts in worker: DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:8000/scripts/c3runtime.js' failed to load. at a (http://localhost:8000/workermain.js:1:475) at http://localhost:8000/workermain.js:1:1812 a workermain.js:1

That's the error on the console and the screen shows black.

Google Chrome Version: Version 76.0.3809.132 (Official Build) (64-bit)

Firefox Version: 68.0.2 (64-bit)

Not using any strange extension, only uBlock on BOTH browsers.

Serving the files using python http.server: python -m http.server 8000 --bind 127.0.0.1

The server is misconfigured. It's sending JavaScript files with the wrong MIME type text/plain instead of the correct application/javascript. See this manual entry on MIME types.

Seems fair, Thanks!
