@import CDN url

[ClementParis016]

Using the following webpack configuration:

module: {
      loaders: [
        {
          test: /\.scss$/,
          loaders: ['style', 'css', 'autoprefixer?browsers=last 2 version', 'sass'],
          include: PATHS.styles
        }
      ]
    },

If I try to import a CSS file from a CDN URL in one of my SASS files, like so:
@import "https://code.getmdl.io/1.1.3/material.indigo-pink.min.css";

I get the following error:

ERROR in ./~/css-loader!./~/autoprefixer-loader?browsers=last 2 version!./~/sass-loader!./app/styles/components/app.scss
Module build failed: CssSyntaxError: css-loader-parser: Z:\css-loader!Z:\_projects\canal-9\canal9_webapp\node_modules\autoprefixer-loader\index.js?browsers=last 2 version!Z:\_projects\canal-9\canal9_webapp\node_modules\sass-loader\index.js!Z:\_projects\canal-9\canal9_webapp\app\styles\components\app.scss:1:1: Unexpected formathttps://code.getmdl.io/1.1.3/material.indigo-pink.min.css
@import https://code.getmdl.io/1.1.3/material.indigo-pink.min.css;

Any idea what I'm doing wrong here?

F*ck me, I've just forgot the url() part:

@import url("https://code.getmdl.io/1.1.3/material.indigo-pink.min.css");

works fine
