Error 400 on js and css files of the extension

Extensions

Hi all,
I’m new to this.
I made a very simple extension using Angular. The local test went perfect. But in the hosted test, all the js and CSS files return error 400 and nothing shows up on the screen except the background
The console doesn’t give me more details.
I wonder if anyone has seen anything similar.
Thank you

Ensure that all of the links to your JS and CSS files are relative, and not absolute.

For example, if your HTML file has a JS file with a src /main.js, that’s an absolute path and will not work, and would either need to be main.js, or ./main.js. The same goes for all links to other files.
