Could not load content for HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE


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:

Source map files, like, 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 /*# */ in bootstrap.min.cssbootstrap.min.js and popper.min.js or download source map files from a Bootstrap 4.1.3 release and put them inside libs directory.
