Loadable.Capture not reporting any modules

This is essentially all my code. I am running Hapi and trying to use react-loadable to server render my React application.

I have added a lot of the missing pieces to the code here.

const location = req.url.pathname
const context = {}
const modules = []

const Router = () => (
  <Switch>
    <Route exact path="/" component={Home} />
    <Route path="/login" component={Login} />
    <Route path="/me" component={Profile} />
    <Route component={NotFound} />
  </Switch>
)

const App = () => (
  <StaticRouter location={location} context={context}>
    <main>
      <Header />
      <Router />
      <Footer />
    </main>
  </StaticRouter>
)

const preloadables = [ Home, Login, Profile, NotFound ]
await Promise.all(preloadables.map(preloadable => preloadable.preload()))

const html = ReactDOMServer.renderToString(
  <Loadable.Capture report={moduleName => modules.push(moduleName)}>
    <App/>
  </Loadable.Capture>
)

// render html

It renders the page correctly, as I see my React app rendered in my browser. Although I do not see any contents of the "Router" unless I disable cache on the server. So the first request renders no router, and the following ones do.

On the server, console.log('modules:', modules) returns modules: [] always. Regardless of cache. So even when I disable cache, refresh the page twice to see the router working, modules is still empty.

npm run start:server
Warning: setState(...): Can only update a mounting component. This usually means you called setState() outside componentWillMount() on the server. This is a no-op.

Please check the code for the LoadableComponent component.
modules []
modules []
modules []
modules []
modules []

I am a bit lost since it should be working.. everything looks okay.
