react cdn引入出现错误

Question

用的是react + ts + craco,没有eject
报错原因：Cannot set property 'cdn' of undefined
如果不用ts就没有这个错误
以下是craco.config.js

const path = require('path');
const { whenProd, getPlugin, pluginByName } = require('@craco/craco');
module.exports = {
  webpack: {
    alias: {
      '@': path.resolve(__dirname, 'src')
    },
    configure: (config) => {
      let cdn = {
        js: [],
        css: []
      }
      whenProd(() => {
        config.externals = {
          react: 'React',
          'react-dom': 'ReactDOM'
        }
        cdn = {
          js: [
            'https://cdnjs.cloudflare.com/ajax/libs/react/18.1.0/umd/react.production.min.js',
            'https://cdnjs.cloudflare.com/ajax/libs/react-dom/18.1.0/umd/react-dom.production.min.js',
          ],
          css: []
        }
      })
      const { isFound, match } = getPlugin(
        config,
        pluginByName('HtmlWebpackPlugin')
      )
      if (isFound) {
        match.options.cdn = cdn // 这行报错
      }
      return config
    }
  },
}

打印下看看是啥内容

console.log(match.options)
