Hi,

I currently have the following configuration:

{ test: /\.scss$/, use: [ { loader: MiniCssExtractPlugin.loader }, { loader: "css-loader" }, { loader: "postcss-loader", options: { parser: 'sugarss' } }, { loader: "group-css-media-queries-loader" }, { loader: "sass-loader" } ] } 

And when I run webpack", I get the following error:

TypeError: Cannot read property 'sourceMap' of null

I can fix the issue easily like this:

{ loader: "group-css-media-queries-loader", options: { sourceMap: false } }

However, it would be cool to be able not to specify any options, for example, for the people who are using the following syntax:

use: [MiniCssExtractPlugin.loader, "css-loader", "postcss-loader", "group-css-media-queries-loader", "sass-loader"]

Currently, the syntax above is not supported.

Cheers
