title: Error on GraphQL : no provided id but the store already contains an id of
body: <p>I am very new to GraphQL and Apollo, and I don't understand what is wrong with the 'aliasEmail' field below. When I add this one to the query, I get this error message. When I remove it from the query, everything works perfectly.
  It is well defined in 'types.graphql' and is just a simple string field. </p>
