The execution result (may contain errors).
The HTTP status code to return under
application/graphql-response+json negotiation.
A request error (parse, validation, operation resolution) is 400; a
mutation over GET is 405. An operation that actually executed is 200
even when a field error nulls data — a field error is not a request
error.
The outcome of a GraphQL execution, carrying an HTTP status code for the transport layer to use.
