Getting Null Reference Exception on working Script ?

I want to get data from a gameobjects to save, but when i try getting data it tells: NullReferenceException: Object reference not set to an instance of an object LevelData.GetData () (at Assets/Scripts/LevelData.cs:25)
But when I'm inspecting gameobject where script is attached, it works perfectly. I don't know if it's my mistake or bug but i'll be glad if someone help me.
LevelData.cs

 using System.Collections;
 using UnityEngine;
 
 public class LevelData : MonoBehaviour
 {
     public static LevelData LD;
 
     public PlaceInfo[] Places;
     public GameObject[] targetplace;
 
     private int i = 0;
 
     private IEnumerator GetPlaces()
     {
         targetplace = GameObject.FindGameObjectsWithTag("Place");
         Places = new PlaceInfo[targetplace.Length];
         yield return new WaitForSeconds(0.5f);
         GetData();
     }
 
     public void GetData()
     {
         foreach (GameObject o in targetplace)
         {
             Places[i].rectX = o.GetComponent<RectTransform>().rect.x;
             Places[i].rectY = o.GetComponent<RectTransform>().rect.y;
             Places[i].rectWidth = o.GetComponent<RectTransform>().rect.width;
             Places[i].rectHeight = o.GetComponent<RectTransform>().rect.height;
             if (o.GetComponent<Place>())
             {
                 Places[i].PlaceType = PlaceInfo.Type.Place;
 
                 Places[i].SilverLock = o.GetComponent<Place>().SilverLock;
                 Places[i].GoldLock = o.GetComponent<Place>().GoldLock;
 
                 Places[i].ProgressNeeded = o.GetComponent<Place>().ProgressNeeded;
                 Places[i].EnergyNeeded = o.GetComponent<Place>().EnergyNeeded;
 
                 Places[i].MinExpOngoing = o.GetComponent<Place>().MinExpOngoing;
                 Places[i].MaxExpOngoing = o.GetComponent<Place>().MaxExpOngoing;
 
                 Places[i].MinGoldOngoing = o.GetComponent<Place>().MinGoldOngoing;
                 Places[i].MaxGoldOngoing = o.GetComponent<Place>().MaxGoldOngoing;
 
                 Places[i].MinGoldCompleted = o.GetComponent<Place>().MinGoldCompleted;
                 Places[i].MaxGoldCompleted = o.GetComponent<Place>().MaxGoldCompleted;
                 Debug.Log("Places Fetched");
             }
             i++;
         }
         i = 0;
         Debug.Log("Done Succesfully.");
     }
 
     public void GetPlacesButton()
     {
         StartCoroutine(GetPlaces());
     }
 }
