I'm trying to call RPC from the script, but it throws a null reference exception.

using UnityEngine;  
using UnityEngine.UI;  
using Photon.Pun;

public class HitVFX : MonoBehaviourPun {  
    [SerializeField] private Slider m_HPSlider = null;  
    private Health m_Health = null;

    public Health Health {  
        get {  
            if (m_Health == null) {  
                m_Health = GetComponent<Health>();  
            }

            return m_Health;  
        }  
    }

    void Start() {  
        m_Health = GetComponent<Health>();  
        Initialize();  
    }

    public void Initialize() {  
        if (m_HPSlider) {  
            SetHPSliderMinMaxValues();  
            UpdateHPSlider(Health.Value);  
        }  
    }

    public void SetHPSliderMinMaxValues() {  
        if (m_HPSlider == null) {  
            return;  
        }  
          
        float maxHealth = Health.MaxValue;  
        SetHPSliderMinMaxValuesInternal(maxHealth);

        print(photonView); // NULL HERE  
        photonView.RPC("SetHPSliderMinMaxValuesInternal", RpcTarget.Others, maxHealth); // THROWING NULL REFERENCE EXCEPTION  
    }

    [PunRPC]  
    void SetHPSliderMinMaxValuesInternal(float maxValue) {  
        m_HPSlider.minValue = 0;  
        m_HPSlider.maxValue = maxValue;  
    }  
}  

Tried refreshing the RPC list in resources doesn't change anything. Using Unity 2019.1.0f2 and PUN 2.33 Lib 4.1.6.3.

Note that the object that has this component is instantiated by PhotonNetwork.Instantiate.

Nevermind, caused by different gameobject using the same component.
