Webpack 4 node modules css - Syntax Error: Unexpected token .(dot)

I'm trying to change my react project client side rendering to server side rendering.

There has a problem when I use my webpack config on css which is well used in my origin project(client side rendering).

It did well on build, but when I execute, it returns syntax error

I use webpack4 & babel7.

This is my webpack.config.js.

const path = require('path');
const nodeExternals = require('webpack-node-externals');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");

const serverConfig = {
  mode: 'development',
  target: 'node',
  node: {
    __dirname: false,
  },
  externals: [nodeExternals()],
  entry: {
    'index.js': path.resolve(__dirname, 'src/server.js'),
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
        }
      },
      {
        test: /\.(woff(2)?|ttf|eot)(\?v=\d+\.\d+\.\d+)?$/,
        loader: 'url-loader',
        options: {
          outputPath: './fonts/',
          name: '[hash].[ext]',
        },
      },
      {
        test: /\.(png|jpg|jpeg|gif|ico|svg)$/,
        loader: 'file-loader',
        options: {
          outputPath: './img/',
          name: '[name].[hash].[ext]',
        },
      },
      {
        test: /\.css$/,
        use: [
          'css-loader',
        ],
      },
    ]
  },
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: '[name]',
  },
};

const clientConfig = {
  mode: 'development',
  target: 'web',
  entry: {
    'client.js': path.resolve(__dirname, 'src/index.js'),
    'bundle.js': path.resolve(__dirname, 'src/containers/App.js'),
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
        },
      },
      {
        test: /\.(woff(2)?|ttf|eot)(\?v=\d+\.\d+\.\d+)?$/,
        loader: 'url-loader',
        options: {
          outputPath: './fonts/',
          name: '[hash].[ext]',
        },
      },
      {
        test: /\.scss$/,
        use: [
          MiniCssExtractPlugin.loader,
          'css-loader',
          'sass-loader',
        ],
      },
      {
        test: /\.(png|jpg|jpeg|gif|ico|svg)$/,
        loader: 'file-loader',
        options: {
          outputPath: './img/',
          name: '[name].[hash].[ext]',
        },
      },
      {
        test: /\.css$/,
        use: [
          MiniCssExtractPlugin.loader,
          'css-loader',
        ]
      },
    ],
  },
  output: {
    path: path.resolve(__dirname, 'dist/assets'),
    filename: '[name]'
  },
  plugins: [
    new MiniCssExtractPlugin({
      filename: '[name].bundle.[hash].css'
    })
  ]
}

module.exports = [serverConfig, clientConfig];

And babel.config.js

const presets = ['@babel/preset-env', '@babel/preset-react'];
const plugins = [
  require('@babel/plugin-proposal-class-properties'),
  require('@babel/plugin-proposal-object-rest-spread'),
  require('@babel/plugin-transform-destructuring'),
  require('@babel/plugin-transform-runtime'),
];

module.exports = {
  presets,
  plugins,
};

I think this is caused by webpack nodeExternals not exclude node_modules well...

How to fix it?
