Question NullReference can't find GameObject (Animator)

Hi Guys i currently have a Problem. I always get a NullReference when trying to get an Animator from my FBX file. I have placed an Object above it and to the Object is a Script attached and now i want to get the Animator of the FBX

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5. using System;
6. using System.Net;
7. using System.Net.Sockets;
8. using System.Text;
9.  
10. namespace game
11. {
12.     public class PlayerMove : MonoBehaviour
13.     {
14.         public float moveSpeed = 3;
15.         public float leftRightSpeed = 4;
16.         public float jumpSpeed = 2;
17.         public UDPSocket listener;
18.         public bool playerJump;
19.         Animator pAnimator;
20.  
21.         void Start()
22.         {
23.             listener = new UDPSocket();
24.             listener.Server("255.255.255.255", 42070);
25.             Console.ReadKey();
26.             pAnimator = gameObject.GetComponentInChildren<Animator>();
27.             playerJump = false;
28.         }
29.         void Update()
30.         {
31.             transform.Translate(Vector3.forward * Time.deltaTime * moveSpeed, Space.World);
32.             playerJump = false;
33.  
34.             if (Input.GetKey(KeyCode.W) || listener.Movement == "jump")
35.             {
36.                 if (this.gameObject.transform.position.x > LevelBoundary.leftSide)
37.                 {
38.                     transform.Translate(Vector2.up * Time.deltaTime * jumpSpeed);
39.                     playerJump = true;
40.                     pAnimator.SetBool("Jump", true);
41.                 }
42.             }
43.             if (Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow) || listener.Movement == "left")
44.             {
45.                 if (this.gameObject.transform.position.x > LevelBoundary.leftSide)
46.                 {
47.                     transform.Translate(Vector3.left * Time.deltaTime * leftRightSpeed);
48.                 }
49.             }
50.  
51.             if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow) || listener.Movement == "right")
52.             {
53.                 if (this.gameObject.transform.position.x < LevelBoundary.rightSide)
54.                 {
55.                     transform.Translate(Vector3.right * Time.deltaTime * leftRightSpeed);
56.                 }
57.             }
58.         }
59.     }
60. }
