question

I'm using Unity.

I'm followed the "Getting Started" post here
https://api.playfab.com/docs/getting-started-with-playfab

I made an empty game object and attached the script to it.
I get these errors:

Error #1

Error logging in player with custom ID:
UnityEngine.Debug:Log(Object)
PlayFabManager:<Login>m__1(PlayFabError) (at Assets/PlayFabManager.cs:33)

Error #2

My Code: (I substituted my GameTitleId with "XXXX" for this post)

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

public class PlayFabManager : MonoBehaviour {

    public string PlayFabId;

    void Login(string titleId)
    {
        LoginWithCustomIDRequest request = new LoginWithCustomIDRequest()
        {
            TitleId = titleId,
            CreateAccount = true,
            CustomId = SystemInfo.deviceUniqueIdentifier
        };

        PlayFabClientAPI.LoginWithCustomID(request, (result) => {
            PlayFabId = result.PlayFabId;
            Debug.Log("Got PlayFabID: " + PlayFabId);

            if(result.NewlyCreated)
            {
                Debug.Log("(new account)");
            }
            else
            {
                Debug.Log("(existing account)");
            }
        },
        (error) => {
            Debug.Log("Error logging in player with custom ID:");
            Debug.Log(error.ErrorMessage);
        });
    }

    // Use this for initialization
    void Start () {
        Login ("XXXX");
    }

    // Update is called once per frame
    void Update () {

    }
}

Please advise what I'm doing wrong or if this is supposed to be the result. I thought it's supposed to create a new player account and return a newly generated PlayFabId?
