Hello,

does anyone know, what to do with this error I am getting when running webpack?

Child

ERROR in ./ClientApp/components/MainMenu/main-menu.less
    Module parse failed: C:\Work\PD2\PD2_HVC_WebService\Application\PD.HVC.WebService\ClientApp\components\MainMenu\main-menu.less Unexpected character '@' (1:1)
    You may need an appropriate loader to handle this file type.
    | @import "../../css/less/_colors.less";
    |
    | .menu-bars {

I assume this error has something to do with serverBundleConfig in webpack.config.js. I am not getting this error when I am running build for client side.

My webpack.config.js loaders looks like this:

    const extractCSS = new ExtractTextPlugin('site.css');
    const extractLESS = new ExtractTextPlugin('build_less.css');
    const clientBundleConfig = merge(sharedConfig(), {
        entry: { 'main-client': './ClientApp/boot-client.tsx' },
        module: {
            rules: [
                { test: /\.css$/, use: extractCSS.extract({ use: 'css-loader' }) },
                {
                    test: /\.less$/,
                    loader: extractLESS.extract({
                        fallback: 'style-loader',
                        use: [
                            'css-loader',
                            'postcss-loader',
                            'less-loader'
                        ]
                    })
                },
                { test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=25000' }
            ]
        },

Hope it makes sense.

Thanks for any help
