We are running Next.js JSS app using XM Cloud docker setup, our localhost:3000 site is loading, but when we are trying to run Experience Editor it is giving 2 erros.

On First Try we are getting below error:

A Sitecore.JavaScriptServices application was not found for the path {itempath}. You should ensure that:
* You have applied a Sitecore configuration patch for the application (see App_Config\Sitecore\JavaScriptServices\Sitecore.JavaScriptServices.ExampleApp.config.example)
> * The path represents a Route
* The Route item is a descendant of an App item

If I change the URL with query string sc_site to sc_jssapp it is giving us below error

2836 06:24:55 ERROR [JSS] Error occurred during POST to remote rendering host: `http://localhost:3000/api/editing/render`

We have already checked JSS_Editing Secret in .env file and Sitecore config.

You make request from Sitecore container. localhost on the Sitecore container is not equal to localhost on your local machine.

enter image description here

Localhost inside container is this container address. You can't request from the Docker container your sites that are hosted on your machine. What you can do: setup rendering host container inside your Docker network and change http://localhost:3000/api/editing/render to the address of your rendering host container, e.g. http://localhost:3000/api/editing/render

    Thanks I am able to resolve both the issues by changing localhost:300 to rendering:3000 and also sc_site querystring param is also working fine by changing app item template and home item template to route template in jss Commented Mar 10, 2023 at 3:01
  • One caveat to this diagram is that you actually can access your machine localhost from containers network, it just has to be with the host host.docker.internal Commented Jan 30 at 21:41
  • @BenSewards Yes, for a major part of containers. But it doesn't work for CM container out of the box! You need to do a little trick to achieve it: exdst.com/posts/…

  • That's informative, I can confirm that I cannot ping it within my local CM on v4.22.1 still, but the node rendering host works. Commented Feb 2 at 20:35

    @BenSewards Yes, it should be the default behavior for all containers according the Docker documentation. But for some reason, it doesn't. And I didn't find the root, of why some containers have this issue host.docker.internal. The easy way was to path hosts file
