title: FaunaDB Graph query returns error Must provide schema definition with query
body: <p>I am  trying to query <strong>FaundaDb</strong> <strong>GraphQL</strong> from my Elm js code. I am using <code>dillonkearns/elm-graphql</code> graph libray in my Elm code</p>
  
  <p>I get the following error message:</p>
  
  <pre><code>{ 
    "data":null,
    "errors":[{
        "message":"Must provide schema definition with query type or a type named 
         Query."}]
  }
  </code></pre>
  
  <p>The Jason request body of the Post to the fauna <strong>api</strong> endpoint is:</p>
  
  <pre><code>{"query":
  query 
     {  
      userByUserName37286792: userByUserName(userName: "user123") 
      {   name    
          games {      
              data {        
                   ...
                  }
              }  
          }
      }
  </code></pre>
  
  <p>If I paste this graph query into the Fauna graph playground it works. When I look at browser debugger to see what is actually sent using this query, the initial "query" word is removed. {  userByUserName37286792 ...</p>
  
  <p>Last point.  I uploaded my scheme file to Fauna with some custom type and a Query section</p>
  
  <pre><code>type Query {
    allUsers: [User]
    userByUserName(userName: String!): User
  }
  </code></pre>
