react-native: res.body is null, only res.text is working

Using react-native 0.4.1, both my request.get and request.post methods are working, but the res.body is undefined, forcing me to manually JSON.parse the res.text:

request
      .post('http://10.0.0.3:9091/auth')
      .type('json')
      .send({
        email: 'xxx',
        password: 'xxx',
      })
      .end((error, res) => {
        if (res.status === 200) {
          console.log(res.body); // undefined
          var token = JSON.parse(res.text).token; // working
...

When calling this from regular React, it’s working perfectly.

same here, if my API return content-type header application/vnd.profiles+json instead of application/json res.body is null and res.text has content.
