errored out during transformation Cannot read property 'constant' of undefined

[adarshmadrecha]

I am using this plugin in documentation site created using vuepress (Vue based static site generator)

// .vuepress/config.js

const OptimizePlugin = require('optimize-plugin');
configureWebpack: {
    plugins: [
      new OptimizePlugin({
        downlevel: false,
      })
    ],
  }
