How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Ensure you have ultimate license on your GDK.
2. Open GraphiQL explorer by visiting [GDK_HOST]/-/graphql-explorer
3. Execute the following query

query {
  namespace(fullPath: "flightjs") {
    complianceFrameworks {
      nodes {
        name,
        color,
        projects {
          nodes {
            id,
            name
          }
        }
      }
    }
  }
}

4. Verify that the above query produces the expected results.
