Problem configuring webpack retry ChunkLoadError plugin

[jbuckner]

We're using the @snowpack/plugin-webpack plugin for optimizing for production. I've been seeing a lot of ChunkLoadError in our logs, which seem to be network-related errors while lazy loading parts of the javascript.

I found a webpack plugin that should auto retry these chunks, but when I configure it, I get this error during the build:

[@snowpack/plugin-webpack] TypeError: The 'compilation' argument must be an instance of Compilation

My snowpack.config.js file looks like this:

const { RetryChunkLoadPlugin } = require('webpack-retry-chunk-load-plugin');
...
module.exports = {
  plugins: [
    [
      '@snowpack/plugin-webpack',
      {
        extendConfig: (config) => {
          const retryPlugin = new RetryChunkLoadPlugin();
          config.plugins.push(retryPlugin);
          return config;
        },
      },
    ]
  ]
}

This is the first webpack plugin I've added to the pipeline so I'm not totally sure if I'm doing this correctly or if there's some issue with the plugin itself.
