Queries returning scalars aren't generated properly

[xfthhxk]

I'm using Lacinia on the server and testing through GraphiQL. I'm not able to generate queries which return scalars.

The following input in GraphiQL appears to be valid:

{getDate}

and returns:

{
  "data": {
    "getDate": "2017-07-13T05:28:11.436Z"
  }
}

As is:

{sayHello(name: "Tom")}

which returns:

{
  "data": {
    "sayHello": "Hello, Tom"
  }
}

I don't see a way to generate queries without specifying the fields to return.

Tried the following:

(venia/graphql-query {:venia/queries [[:getDate]]}) 

Which throws

Unhandled clojure.lang.ExceptionInfo
   Invalid query data
   #:venia{:ex-type :venia/spec-validation, :ex-explain nil}
