Error to compile .sass syntax

When i add bulma framework with .sass syntax have this error:

Media query expression must begin with '('

Without this, works fine.

My loader:

{
        test: [/\.[s]css$/, /\.sass$/],
        loader: ExtractTextPlugin.extract({
                loader: ["css-loader", "sass-loader"]
        })
}

Any suggestions?

Yes, can close.

You don’t need to set the option explicitly anymore. The sass-loader derives it automatically for files ending on .sass
