I have a simple express graphql server:

const schema = require('./schema');
const express = require('express');
const graphqlHTTP = require('express-graphql');
const cors = require('cors')
const bodyParser = require('body-parser');


const app = express();
app.use(cors());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

app.use('/graphql', graphqlHTTP(req => {
  return ({
  schema,
  pretty: true,
  })
}));

const server = app.listen(9000, err => {
  if (err) { return err; }
  console.log(`GraphQL server running on http://localhost:${9000}/graphql`);
});

And my request looks like:

Any help?

• Try replacing schema, with schema: schema, – user5734311 Commented Aug 6, 2017 at 9:37
• @ChrisG it would have throw Syntax error, if it didnt understand the syntax. – Avraam Mavridis Commented Aug 6, 2017 at 9:40
• @ChrisG In ES6 { schema } is equivalent to { schema: schema }. It's syntactic sugar! Good eye, though: this looks like a bug. – Ziggy Commented Oct 10, 2017 at 3:51

You need to specify application/json in your Content-Type header -- you currently have text/plain. You've included the body parser middleware on the server, but it relies on that header in your request to know when it needs to actually parse the response into JSON.
