introspectionQuery cant work

[charlzyx]

Here is my code

var introspectionQuery = require('graphql/utilities').introspectionQuery;
var request            = require('sync-request');
var response = request('GET', graphqlHubUrl,{
    qs:{
        query: introspectionQuery
    }
});

I get an Error Module build failed: Error: Invalid introspection data supplied togetBabelRelayPlugin(). The resulting schema is not an object with a__schemaproperty.
then i check code and found something make this error
I test by http://graphql-swapi.parseapp.com/ and
https://www.graphqlhub.com/playground

//graphql-js/src/utilities/introspectionQuery.js
  query IntrospectionQuery {
    __schema {
      queryType { name }
      mutationType { name }
      subscriptionType { name }
      types {
        ...FullType
      }
      directives {
        name
        description
// HERE IS IT! the `locations` make query error , and delete this can work well
        locations
        args {
          ...InputValue
        }
      }
    }
  }

all query

  query IntrospectionQuery {
    __schema {
      queryType { name }
      mutationType { name }
      subscriptionType { name }
      types {
        ...FullType
      }
      directives {
        name
        description
        locations
        args {
          ...InputValue
        }
      }
    }
  }

  fragment FullType on __Type {
    kind
    name
    description
    fields(includeDeprecated: true) {
      name
      description
      args {
        ...InputValue

  fragment InputValue on __InputValue {

    type { ...TypeRef }
    defaultValue
  }

  fragment TypeRef on __Type {

Perhaps you're passing in an object that looks like { data: { __schema: ... } } and you just need to unwrap the data property?

Hey @ifelsee thanks for opening this issue! You're getting this error because you are executing a modern introspection query that asks for the locations field on the directive type, but the GraphQL servers you're hitting are running an older version from before the locations field was added.

We added support for directive locations here.

If you're just using these two GraphQL endpoints for testing and have control over your own GraphQL endpoint, upgrading to a newer version of GraphQL-js (>0.5.0) will support the locations field on directives. If this workaround is sufficient, please go ahead and close this issue.

We've deployed an updated SWAPI sample that should work with the introspection query you pasted: https://swapi-graphql.now.sh/. As for graphqlhub, there is already an open issue: clayallsopp/graphqlhub#37.
