FBSDKGraphRequest in React Native returning incomplete object - ios

Question

So I have implemented the react native FBSDKGraphRequest and login button. Login is working correctly, but when i attempt a graph request of the user, instead of the complete object i expect the /me endpoint to return
{
"id": "162036280799349",
"birthday": "08/08/1980",
"email": "test_ppjeffg_eight\u0040tfbnw.net",
"first_name": "Test",
"gender": "male",
"last_name": "Eight",
"link": "https://www.facebook.com/app_scoped_user_id/162036280799349/",
"locale": "en_US",
"name": "Test Eight",
"timezone": -8,
"updated_time": "2015-07-28T18:22:16+0000",
"verified": false
}
I just get
Object {name: "Test Eight", id: "162036280799349"}
I very well may be doing the request incorrectly, though I've done everything according to documentation. Here is the relevant source code:
class LoadingOverlay extends BaseComponent{
constructor(props){
super(props);
this._bind(/*'_fetchFriendsRequestFunction'*/);
this.state = {isVisible: true,
token: null,
profileInfo: null}
}
_fetchGraphRequestFunction(){
console.log("start");
var fetchProfileRequest = new FBSDKGraphRequest((error, result) => {
if (error) {
alert('Error making request.');
} else {
// Data from request is in result
console.log(result);
}
}, '/me');
// Start the graph request.
fetchProfileRequest.start();
}
render(){
return(
<Overlay isVisible={this.state.isVisible}>
<BlurView style={styles.background} blurType="dark">
<FBSDKLoginButton
onLoginFinished={(error,result)=>{
if (error){
alert('Error Logging In.');
} else {
if (result.isCanceled){
alert('Login Cancelled.');
} else {
FBSDKAccessToken.getCurrentAccessToken((token)=>{
console.log(token.tokenString);
this._fetchGraphRequestFunction();
})
}
}
}}
onLogoutFinished={()=>console.log('Logged Out.')}
readPermissions={['public_profile', 'email', 'user_birthday', 'user_friends']}
publishPermissions={['publish_actions']}/>
</BlurView>
</Overlay>
);
}
}`

You can request additional parameters from Facebook by either appending them to the uri like this:
/me?fields=id,name,email
or by calling the addStringParameter function on the FBSDKGraphRequest object like this:
fetchProfileRequest.addStringParameter('picture,email,gender','fields');
However, what fields you get in return depends on the permission of your app and the settings of the user.
Also, note this little trick from the ios FB sdk documentation: https://developers.facebook.com/docs/reference/ios/current/class/FBSDKLoginButton/
Note, that if read permissions are specified, then publish permissions should not be specified.
So try sending an empty publishPermissions parameter and see if that fixed it.
More information here:
Publish or manage permissions are not permited to to be requested with read permissions FACEBOOK SDK

I'd love to see an example of the flow to make this work in react native if anyone has it.
