Description

The graphQL server throws an InvalidOperationException("Cannot execute request if no query is specified") when HTTP GET is requested on graphql endpoint.

This is a very common scenario (people opening the graphql endpoint in browser). It is causing an internal server error. It would be better if the GraphQL framework could handle this situation. Instead the error is propagated to ASP.NET middleware.

Steps to reproduce

Open url http://{server}/graphql in browser which points to the graphql endpoint.

Expected result

Bad http request (400)

Actual result

Unhandled exception is thrown.
Returned Http Response 500.
