Javascript 为Shopify开发设置webpack/HMR

我正在尝试设置webpack的开发服务器和HMR，以配合Shopify主题开发。当运行服务器并打开本地IP时，我从Shopify的DNS提供商CloudFlare那里得到了这个错误

如何正确设置网页包，将热更改（css/JS）注入我的代理Shopify商店（mystore.myshopify.com url）？

我的网页包配置如下：

const path = require("path");
const BrowserSyncPlugin = require('browser-sync-webpack-plugin');

module.exports = {
  mode: "development",
  devServer: {
    contentBase: false,
    hot: true,    
    https: true,
    proxy: {
      "**": { 
        target: "http://mystore.myshopify.com", 
        secure: false
      }
    },    
  },  
  entry: "./src/scripts/index.js",
  output: { 
    filename: "./app.js",
    path: path.resolve(__dirname, "dist")
  },
  plugins: [

  ],
  module: {
    rules: [
      {
        test: /\.s[ac]ss$/i,
        use: [
          // Creates `style` nodes from JS strings
          'style-loader',
          //postcss here (autoprefixer, babel etc)
          // Translates CSS into CommonJS
          'css-loader',
          // Compiles Sass to CSS
          'sass-loader',
        ],
      },
    ],
  },
};
