How to compile 2 less files into 2!!! css file to a specific location?

Question

css

Initial layout in less. We need to make sure that media requests are disabled -> we take out the main styles in app.less, media - in media.less. Now it remains to compile 2 css files from them and put them in a certain place.
I took https://github.com/vikpe/react-webpack-babel-start... as a basis , this blank. Here is webpack 3, more or less fresh react, and so on.
I put less-loader, I register in common.js

{
            test: /\.less$/,
            use: [{
                loader: "style-loader" // creates style nodes from JS strings
            }, {
                loader: "css-loader" // translates CSS into CommonJS
            }, {
                loader: "less-loader" // compiles Less to CSS
    }],
    },

in react component I import: import 'assets/less/app.less'; and import 'assets/less/media.less';
Everything works, but less was not recompiled into a css file, but embedded into html. In short, it's not. Next in the docs is the option for prod (It's generally recommended to extract stylesheets to a separate file created with ExtractTextPlugin . This way your styles don't depend on JavaScript) Change prod.js to

// production config
const merge = require('webpack-merge');
const {resolve} = require('path');

const commonConfig = require('./common');

const ExtractTextPlugin = require("extract-text-webpack-plugin");
 
const extractLess = new ExtractTextPlugin({
    filename: "[name].[contenthash].css",
    disable: process.env.NODE_ENV === "development"
});

module.exports = merge(commonConfig, {
  entry: './index.js',
  devtool: 'source-map',
  output: {
    filename: 'js/bundle.[hash].min.js',
    path: resolve(__dirname, '../../dist'),
    publicPath: '/',
  },
  module: {
        rules: [{
            test: /\.less$/,
            use: extractLess.extract({
                use: [{
                    loader: "css-loader"
                }, {
                    loader: "less-loader"
                }],
                // use style-loader in development
                fallback: "style-loader",
          publicPath:"/css/"
            })
        }]
    },
    plugins: [
        extractLess
    ]
});

and as a result:
1. all styles are written in one css file (and I need 2), and not where I specified in publicPath.
2. errors in npm-debug.log
