Object not set to a instance of a object

I have no clue what I am doing wrong.

 using UnityEngine;
 using System.Collections;
 
 public class CameraScript : MonoBehaviour

     [SerializeField]
     private Transform target = null;[SerializeField]
     private float distance = 3.0f;[SerializeField]

     [SerializeField]
     private Vector3 targetLookAtOffset; // allows offsetting of camera lookAt, very useful for low bumper heights
     [SerializeField]
     private float bumperDistanceCheck = 5f; // length of bumper ray
     [SerializeField]
     private float bumperCameraHeight = 1.0f; // adjust camera height while bumping
     [SerializeField]
     private Vector3 bumperRayOffset; // allows offset of the bumper ray from target origin
     private Transform Player;                        /// <Summary>

     private void Awake()
     {
         GetComponent<Camera>().transform.parent = Player;
     }
     private void FixedUpdate()
     {
         Vector3 wantedPosition = Player.TransformPoint(0, height, -distance);
         // check to see if there is anything behind the target
         RaycastHit hit;
         Vector3 back = Player.transform.TransformDirection(-1 * Vector3.forward);
         // cast the bumper ray out from rear and check to see if there is anything behind
         if (Physics.Raycast(Player.TransformPoint(bumperRayOffset), back, out hit, bumperDistanceCheck)

         }
         transform.position = Vector3.Lerp(transform.position, wantedPosition, Time.deltaTime * damping);
         Vector3 lookPosition = Player.TransformPoint(targetLookAtOffset);
         if (smoothRotation)
         {

             transform.rotation = Quaternion.Slerp(transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
         }
         else
