PlayFab: Getting player title data with leaderboard?

I have a player title data key I want to get as I get the leaderboard data. Right now, all the leaderboard stuff works, and I can print the data key values, but I'm not sure how to apply those values to the instantiated leaderboard entry prefabs, as they are instantiated within the "OnLeaderboardTimeTrialsGet" and not the "SendOtherPlayersEquippedShip".

     void OnLeaderboardTimeTrialsGet(GetLeaderboardResult result)
     {
     foreach (var item in result.Leaderboard)
             {
                 GameObject newGo = Instantiate(ttPrefab, ttParent);
     
                 //Changing text of the "ttPrefab" to show display name, score, etc
     
                 string playerId = item.PlayFabId;
     
                 GetOtherUserShipTTEntry(playerId);
             {
     }
         public void GetOtherUserShipTTEntry(string id)
         {
             PlayFabClientAPI.GetUserData(new GetUserDataRequest()
             {
                 PlayFabId = id,
                 Keys = null
             }, result =>
             {
                 foreach (var item in result.Data)
                 {
                     int shipEntry = 0;
                     if (result.Data != null)
                     {
                         shipEntry = int.Parse(result.Data["Ship"].Value);
                     }
                     else
                     {
                         shipEntry = 0;
                     }
                     SendOtherPlayersEquippedShip(shipEntry + 6);
                     Debug.Log(shipEntry);
                 }
             }, error => { });
         }
     
         public void SendOtherPlayersEquippedShip(int entry)
         {
             foreach (var child in ttParent)
             {
                 GameObject shipImage = child as GameObject;
                 if (entry == null)
                     entry = 0;
                 GameObject shipChild = shipImage.transform.GetChild(entry).gameObject;
                 shipChild.SetActive(true);
             }
         }

The ttPrefab is a UI gameobject with 3 text children for name, score, and position. It also has images of ships I want to display based on what the player title data key returned. Right now I get the:

NullReferenceException: Object reference not set to an instance of an object

error, which makes sense. I'm just not sure how to fix it.
