Source mapping error: Error: request failed with status 404 in CSS and JS files

  • 772

I'm making a web, and I get these errors on the console. Everything worked fine before, I didn't make any changes to the project's native path, the project is in codeigniter 3, I don't know what's going on

Source mapping error: Error: request failed with status 404

mistake

If someone can explain to me why this happens, the routes are fine, when I click one of those routes it redirects me to the css/js

This is my vendor directory in assets assets

enter image description here

    The message is not a serious error, it is only indicating that the sourcemap (.map file) associated with the .js or .css resource could not be found (but the js and css files are being loaded)

    Typically minified files have a trailing line indicating the presence of a sourcemap file:

    For example: in https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js your last line:

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

    This indicates that there is an associated sourcemap at https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js.map

    The browser automatically tries to download this additional file (it is not essential, but it is useful for debugging or accessing the source of the minified code)

    Therefore, only essential files ( .jsand ) may have been uploaded to the site but not their associated y .cssfiles . You can find a way to include these files in the site load, remove this last line from the files, or simply dismiss these messages..css.map.js.map
