I can't count the values scriptable object

Question

I'm writing a game where I'm using scriptable objects for the first time. And I ran into an error. "NullReferenceException: Object reference not set to an instance of an object". I have no idea how to solve this problem, but I really need to do it. I've tried using the Start method, Awake, and even calling a separately created method, which checks to see if the values are set when any method is executed. I need to somehow read the data from the scriptable object in order to enter it into the fields of the class. However, I do not know of any method that could allow me to do this. Tell me what can be used, or how to read the data. enter image description here

using UnityEngine;
using UnityEngine.EventSystems;

public class OnEntityClickHandler : MonoBehaviour, IPointerClickHandler
{
    public void OnPointerClick(PointerEventData eventData)
    {
        Skeleton skeleton = gameObject.GetComponent<Skeleton>();

        skeleton.TakeDamage(GetDamage(skeleton.Type));
    }

    private uint GetDamage(IElement elementType)
    {
        uint totalDamage = 0;

        foreach(GameObject i in PerkController.Perks)
        {
            Perk perk = i.GetComponent<Perk>();

            totalDamage += perk.GetDamage(elementType); // Error
        }

        return totalDamage;
    }
}

using UnityEngine;

public class Perk : MonoBehaviour
{
    [SerializeField]
    private PerkData _data;
    [SerializeField]
    private GameObject _upgradeDrop;

    private string _name;
    private string _description;
    private uint _upgradeCost;
    private uint _damage;
    private IElement _type;

    private uint _level = 1;
    private float _index = 1.5f;

    public string Name => _name;

    private void Start()
    {
        _name = _data.Name;
        _description = _data.Description;
        _upgradeDrop = _data.UpgradeDrop;
        _upgradeCost = _data.UpgradeCost;
        _damage = _data.Damage;
        _type = ElementController.GetElement(_data.Type);
    }

    public uint GetDamage(IElement elementType)
    {
        return (uint)(_type.GetIndex(elementType) * _damage * _level);
    }

    public bool TryUpgrade()
    {
        string upgradeDropName = _upgradeDrop.GetComponent<Drop>().Name;

        if (DropController.TryDecreaseCount(upgradeDropName, _upgradeCost))
        {
            _level++;
            _upgradeCost = (uint)(_upgradeCost * _index);

            return true;
        }
        else
        {
            return false;
        }
    }
}

using UnityEngine;

public class PerkController : MonoBehaviour
{
    [SerializeField]
    private GameObject[] _perks;

    public static GameObject[] Perks;

    private void Start()
    {
        Perks = _perks;
    }
}
