NullReferenceException: Object reference not set to an instance of an object when looking up an object. What to do?

Question

Unity

Throws the error "NullReferenceException: Object reference not set to an instance of an object sceneMan.OnTriggerEnter2D (UnityEngine.Collider2D collision) (at Assets/sceneMan.cs:14)" when I try to find an empty object with a tag or title.
Here is the script:

using UnityEngine;
using UnityEngine.SceneManagement;
public class sceneMan : MonoBehaviour
{
    public bool nStory;
    public int id;
    private void OnTriggerEnter2D(Collider2D collision)
    {
        SceneManager.LoadScene(int.Parse(name));
        if (nStory)
        {
            Debug.Log("ppos"+id);
            Debug.Log(GameObject.Find("Player").name);
            Debug.Log(GameObject.FindGameObjectWithTag("ppos").name);
            GameObject.Find("Player").transform.localPosition = GameObject.Find("ppos" + id).transform.localPosition;
        }
    }
}

Answer 1

Debug. Surely it was not possible to simply find the object. Why is hard to say. Maybe he's not on stage at all. Or maybe the scene does not have time to load normally.
