I'm developing an HTML CSS Website and I'm getting this error and similar. I've seen a couple of answers where it says that you need to go to Developer Tools in your browser and fix it there but I've tried in every browser and I think the problem is within the code can someone help me with it?

Referring to Vitaliy-1's soultion here. You could either add source map files or remove the source map reference.

This error means that browser can't find the file pointed here: https://github.com/pkp/healthSciences/blob/master/libs/bootstrap.min.css#L7

Source map files, like bootstrap.min.css.map, are generated automatically during files minification/compiling process. They actually are not needed for the production, but at the same time occupy 3 times more disk space than ones which they are mapping. That's why I don't include them in the release.

If you want just to remove that message, you can either remove comments like /*# sourceMappingURL=bootstrap.min.css.map */ in bootstrap.min.css, bootstrap.min.js and popper.min.js or download source map files from a Bootstrap 4.1.3 release and put them inside libs directory.
