Description
After installing the plugin via yarn, and importing it into my `development.js` config, I get this error `TypeError: Cannot read property 'afterEmit' of undefined` when I run `webpack-dev-server --hot`
I am using this plugin in a rails app using webpacker.
My webpacker version: "@rails/webpacker": "^3.5.3"
And here's my `development.js` config
```
process.env.NODE_ENV = process.env.NODE_ENV || 'development'
const environment = require('./environment')
const WebpackLighthousePlugin = require('webpack-lighthouse-plugin')
environment.plugins.append(
'WebpackLighthousePlugin',
new WebpackLighthousePlugin({
url: 'http://localhost:3000'
})
)
module.exports = environment.toWebpackConfig()
```
Do I need to upgrade webpacker? Saw a similar issue over [here](https://github.com/MikaAK/s3-plugin-webpack/issues/105) for another plugin
