Node render engine project directory path '{website-path}\app' does not exist

Question

We reently moved Sitecore First from CodeFirst. Which means we have deployed jss app to the Sitecore. But when we try to open Exprience Editor, we face below issue:

Error Rendering Sitecore.JavaScriptServices.ViewEngine.Presentation.JsLayoutRenderer: Node render engine project directory path '{website-path}\app' does not exist. Ensure your JavaScript code has been deployed and that the configured path is correct.

   at Sitecore.Mvc.Pipelines.Response.RenderRendering.ExecuteRenderer.Render(Renderer renderer, TextWriter writer, RenderRenderingArgs args)

Any clue as to what's missing in here?

When you open Experience Editor or try to open the page, Sitecore tries to find a jss app with the same name as a context site. As far as I see, the site has the "app" name. I suppose your JSS app has different name. You need to synchronize your jss app and site names.
