Following the tutorial everything is looking good. The app deploys with no errors using jss deploy app --includeContent --includeDictionary.

I can see the content in Sitecore so thats all good.

However when I view the site I get the following error:

Error Rendering Sitecore.JavaScriptServices.ViewEngine.Presentation.JsLayoutRenderer: GraphQL error: Unknown type GraphQLConnectedDemo. GraphQL error: Unknown type AppRoute. GraphQL error: Unknown type AppRoute. Error: GraphQL error: Unknown type GraphQLConnectedDemo. GraphQL error: Unknown type AppRoute.

Any ideas?


  • Check also that the site templates, if any, are published. This issue is caused by the site's GraphQL API not being able to find an expected template in Sitecore - and thus not exposing that type to GraphQL. If you load up /api/jssappname/ui?sc_apikey={yourapikey} that may provide insights into what is available and what is not in GraphQL. The Docs button will let you browse the schema. – Kam Figy Nov 8 '18 at 18:58

I also had this same error, for me the issue was that I'd used the wrong url during jss setup.

Check /scjssconfig.json in your React project and verify that "deployUrl" and "layoutServiceHost" match what is configured in sitecore in App_Config\Include\zzz\<your project name>.config under <site hostname="">.


Recycling the IIS app pool once will resolve this issue. This is a bug that we fixed in the generally available release.
