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?
