React + Flux, ES6, Babel ActionCreate using json-server and super agent, data not in response

Hello I am attempting to use json-server to mock up the api of an React Flux ES6 app I am building. But when I user the superagent node module to make the request from the action creator the data in the callback is undefined

Here's my code

import Dispatcher from '../Dispatcher';
import Constants from '../Constants';
import request from 'superagent';

export default {
setQuestions(guides) {
Dispatcher.handleViewAction({
type: Constants.ActionTypes.SET_QUESTIONS,
data: guides
});
},

getQuestionsFromServer() {
let self = this;
let destination = 'http://localhost:3000/questionnaires';
// request from json service.
request
.get(destination)
.set({
'X-Requested-With': 'XMLHttpRequest'
})
.end(function(response) {
// response is empty. why???
if (response.ok) {
let guideData;
guideData = response.body;
self.setQuestions(guideData);
}
});
}
};


My network tab says the request happens but I cannot access the response in the callback.

Answer

I figured out how to make this xhr request without superagent node module by using the fetch es2015. See here: https://developer.mozilla.org/en-US/docs/Web/API/GlobalFetch/fetch

getQuestionsFromServer() {
    let self = this;
    let destination = 'http://localhost:3000/questionnaires';
  // request from json service.response.json()
  fetch(destination)
        .then(response => response.json())
    .then(data => {
          this.setQuestions(data[0].questions);
      })
      .catch(e => console.log("Error", e));

}

Thanks!
