Can't

[truca]

My application is working in production and works perfectly with graphiql, but i'm getting this response when i use this package:

{ raw: '{"errors":[{"message":"Must provide query string."}]}', data: undefined, errors: [ { message: 'Must provide query string.' } ], headers: { 'x-powered-by': 'Express', 'access-control-allow-origin': '*', 'content-type': 'application/json; charset=utf-8', 'content-length': '53', etag: 'W/"35-1vperDe+r7EpHry/i+J3wg"', date: 'Sun, 17 Sep 2017 17:39:45 GMT', connection: 'close' }, status: 400, success: false }

What can i do to make it work?
