Troubleshooting Sitecore JSS: Resolving the "Provided SSC API Key is Not Valid" Error

 

Recently, while doing another setup, I got this error 

Solution - First try to hit this URL 

It's related with the Jss API, make sure that you have created a new API key here 

Try to this this URL to confirm if the GraphQL service is running

https://sitecore103sc.dev.local/api/graph/items/master/ui?sc_apikey={AC48C51E-DDFF-48E5-BA2A-1884CE9CCBF2}

When I hit this URL, I got below error 

Follow this document to setup the GraphQL - https://doc.sitecore.com/xp/en/developers/hd/21/sitecore-headless-development/start-using-sitecore-graphql-api.html

Here are the steps

1. Update this configuration to true 

<compilation debug="true">.

Enable the master GraphQL file 

After this change, I got a different error while browing GraphQL service

Now, at this stage, try to hit the GraphQL UI

https://sitecore103sc.dev.local/sitecore/api/graph/items/master/ui

I go this error 

{"errors":[{"message":"Authentication required."}]}

Make below change to Sitecore.Services.GraphQL.config

Finally to make it work, you have to make the below change  (This was the main change in my scenario)

Go to 

C:\inetpub\wwwroot\Sitecore103sc.dev.local\App_Config\Sitecore\Owin.Authentication\Sitecore.Owin.Authentication.config

add this line 

<path>/sitecore/api/graph/items</path> under       </siteNeutralPaths>

After that change, I can browser the GraphQL through the UI

Please note, it's recommned that you should not enable these GraphQL end point on prodution for the security purpose, all these changes I'm doing is just for the local setup.

but still, I got the authentication error , I'm running below query

query {

  # path can be an item tree path or GUID-based id

  item(path: "/sitecore/content/Experience-Edge/home", language: "en") {

    # items can be cast to a Template type with inline fragments

    ... on AppRoute {

      pageTitle {

        value

      }

    }

    # fields can be cast to a Field type with inline fragments

    field(name: "pageTitle") {

      ... on TextField {

        value

      }

    }

  }

}

I made the below changes to the API key, related to the CORS but it didn't help 

After this change, I start the  JSS application but got the below error 

rror: GraphQL.ExecutionError: Error trying to resolve layout. ---> System.ArgumentNullException: Value cannot be null.

After this change, I restated my system and it started working
