Module not found. attempted require...

I get an error when using prerender-loader. It seems to fail with the below error. I traced it to this line and it appears that the only keys in compilation.assets are ssr-bundle.js. Any suggestions?

I know this is a real issue, but this plugin isn’t designed to be used in development mode (with hot-reloading libraries): you should only need to apply it on a production build (with no added code from webpack hot-reloading libraries)

Regarding conditional escaping, you can do this:

if (self.PRERENDER) {
  // code is being run in prerender-loader
}
else {
  // code is being run in browser
}
