Hi, getting the Critical Dependency error when using express with hot module.

WARNING in ./packages/servers/express/node_modules/colors/lib/colors.js
127:29-43 Critical dependency: the request of a dependency is an expression

WARNING in ./packages/servers/express/node_modules/express/lib/view.js

webpack.config.server.js

const webpack = require('webpack');
const path = require('path');
const nodeExternals = require('webpack-node-externals');
const StartServerPlugin = require('start-server-webpack-plugin');

module.exports = {
  entry: [
    'babel-polyfill',
    'webpack/hot/poll?1000',
    path.join(__dirname, '../packages/servers/express/server/index.js')
  ],
  watch: true,
  target: 'node',
  externals: [
    nodeExternals({
      whitelist: ['webpack/hot/poll?1000']
    })
  ],
  resolve: {
    alias: {
      handlebars: 'handlebars/dist/handlebars.js'
    }
  },
  module: {
    rules: [
      {
        test: /\.js?$/,
        use: 'babel-loader',
        exclude: /node_modules/
      }
    ]
  },
  plugins: [
    new StartServerPlugin('server.js'),
    new webpack.NamedModulesPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    new webpack.DefinePlugin({
      'process.env': { BUILD_TARGET: JSON.stringify('server') }
    })
  ],
  output: {
    path: path.join(__dirname, '../packages/servers/express/.build'),
    filename: 'server.js'
  }
};

Thanks
