      The `prerender` option to allow Server Side Rendering is marked as true but the ReactOnRails configuration
      for `server_bundle_js_file` is nil or not present in `config/initializers/react_on_rails.rb`.
      Set `config.server_bundle_js_file` to your javascript bundle to allow server side rendering.
