Quick Bug Sample

yarn
yarn start

3 Servers will be spun up.

Server 1

This is a simple service with 2 types and 2 queries

Server 2

This is a simple service with 3 types and one query

Server

This combines the 2 remote services server1 and server2 and transforms the User type to add in a sites function

Hitting http://localhost:4000/ with the payload

{
	quizzes{
		title
		questions{
			title
		}
		player {
			displayName
			sites {
				title
			}
		}
	}
}

Will give you the error
