What is the endpoint to pass to bundlerUrl when hosting the bundler?

[GKachaner]

Hi all,

I am looking to host the bundler and have followed the steps here : https://sandpack.codesandbox.io/docs/advanced-usage/client#hosting-the-bundler

After the last step i get the following output in the console :

  app: The www folder is ready to be deployed.
  app: You may also serve it locally with a static server:
  app:   npm install -g pushstate-server
  app:   pushstate-server build
  app:   open http://localhost:9000

But the exact endpoint is not specified, and http://localhost:9000 returns an error.
Where could I find the endpoint to pass to bundlerURL please ?

Thanks in advance,
Regards.
