Empty div. No errors anywhere.

This is a project I'm attempting to get working. You have to bundle install that, then do

node hypernova.js
./bin/rails s
./bin/webpack-dev-server

And then access /hello/index

It works fine, but the problem is, is the main div isn't server rendered at all. I'm new to rails but I didn't see any errors anywhere.
