question

I'm newbie about backend and really need help with getuserdata. I have managed to integrate my game with PlayFab's Kongregate Add-on. SetUserData works fine. I can see players saved key/value pairs on my game manager. When I try to copy the GetUserData code sample from documentation, PlayFabId = PlayFabId code line isn't working.

using PlayFab;
using PlayFab.ClientModels;
using UnityEngine;
using UnityEngine.UI;
using System.Collections.Generic;


public class KongregateHandler : MonoBehaviour

{
    public void Start()
    {
        // Utility: show feedback
        SetMessage("Loading kongregate api...");


        /* 
         * Important: execute Javascript in the external context to initialize
         * Kongregate API, Unity Support and set up callback GameObject and Method.
         * In this case, callback is set to a GameObject called Kongregate and a 
         * method called OnKongregateAPILoaded, which we define later in this class.
         * Once Kongregate API is initialized, Unity will locate this object by name 
         * ("Kongregate") and execute a method "OnKongregateAPILoaded" passing in user 
         * info string as an argument. 
         */
        Application.ExternalEval(
          "if(typeof(kongregateUnitySupport) != 'undefined'){" +
          " kongregateUnitySupport.initAPI('Kongregate', 'OnKongregateAPILoaded');" +
          "} else {" +
          " console.error('No unity support!');" +
          "};"
        );
    }


    /*
     * Executed once Kongregate API is ready. This method is invoked by KongregateAPI 
     * and receives a structured text with multiple pieces of data you must parse manually. 
     * The userInfo string parameter has the following structure: 'user_identifier|user_name|auth_token'
     */
    public void OnKongregateAPILoaded(string userInfo)
    {
        SetMessage("Recieved user info! Logging though playfab...");


        // We split userInfo string using '|' character to acquire auth token and Kongregate ID.
        var userInfoArray = userInfo.Split('|');
        var authTicket = userInfoArray[2];
        var kongregateId = userInfoArray[0];


        LogToBrowser("Auth Token: " + authTicket);
        LogToBrowser("Kongregate Id: " + kongregateId);


        /* 
         * We then execute PlayFab API call called LoginWithKongregate.
         * LoginWithKongregate requires KongregateID and AuthTicket. 
         * We also pass CreateAccount flag, to automatically create player account.

        PlayFabClientAPI.LoginWithKongregate(new LoginWithKongregateRequest
        {
            KongregateId = kongregateId,
            AuthTicket = authTicket,
            CreateAccount = true
        }, OnLoggedIn, OnFailed);
    }

     * and display them using Text message label.
