bootstrap.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

Ask Question

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?

DevTools failed to load SourceMap: Could not load content for http://envio.ae/js/bootstrap.min.js.map : HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

DevTools failed to load SourceMap: Could not load content for http://xxxxxx.com/css/aos.css.map : HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

since


    http://envio.ae/js/bootstrap.min.js

has the final line


    //# sourceMappingURL=bootstrap.min.js.map

and


    http://envio.ae/js/bootstrap.min.js.map

does not exist, unless that is YOUR site, there's nothing YOU can do about it - if it is YOUR site, then you need to make sure that file exists – Jaromanda X Oct 25, 2020 at 2:50

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.
