Can't access a method from another script (Object reference not set to an instance of an object)

Hello community!

I have a script Called Projectile where I have some code in order to be able to do object pooling in it and in my Character Controller Script I have set a quick test to try things out and see if the calling method works but I get the object reference not set and I can't figure my way out of it.

Can anyone help me out please?

 public class Projectile : MonoBehaviour
 {
     public Transform target;
 
     public float moveSpeed = 100f;          // speed at which the projtive moves towards the target
     public float rotationSpeed = 10f;      // speed at which the project rotates towards the target
     public float shootTime = 1f;
 
     public bool updateRotation = false;     // whether or not the projectile should continue to update its rotation after it was spawned
     public int pooledAmount = 3;         // max amount of arrows that will be able to be shoot at once
 
     public GameObject arrow;
     public List<GameObject> arrows;            // create a list containing all the arrows that will be allocated to memory once it starts
 
     void Start()
     {
         transform.LookAt(target);   // set the default direction of the projectile to face towards the target
         arrows = new List<GameObject>();
         for (int i = 0; i < pooledAmount; i++)
         {
             GameObject obj = (GameObject)Instantiate(arrow);
             obj.SetActive(false);
             arrows.Add(obj);
         }
     }
 
     void Update()
     {
         Rotate();
         Move();
     }
 
     /// <summary>
     /// Rotates the projectile towards the target.
     /// </summary>
     void Rotate()
     {
         Vector3 targetPosition = target.position - transform.position;
 
         float speed = rotationSpeed * Time.deltaTime;
 
         Vector3 targetDirection = Vector3.RotateTowards(transform.forward, targetPosition, speed, 0);
 
         transform.rotation = Quaternion.LookRotation(targetDirection);
     }
 
     /// <summary>
     /// Move the projectile towards the target.
     /// </summary>
     void Move()
     {
         transform.position = Vector3.MoveTowards(transform.position, target.position, moveSpeed * Time.deltaTime);
     }
 
     /// <summary>
     /// "Destorys" the object
     /// </summary>
     void OnEnable ()
     {
         Invoke("Destroy", 2f);
     }
     void Destory ()
     {
         gameObject.SetActive(false);
     }
     void OnDisable ()
     {
         CancelInvoke();
     }
 
     public void Fire()
     {
         for (int i = 0; i < arrows.Count; i++)     // loops through the list
         {
             if (!arrows[i].activeInHierarchy)      // if the arrow is not currently active (looking for inactive arrows)
             {
                 arrows[i].transform.position = transform.position;
                 arrows[i].transform.rotation = Quaternion.identity;
                 arrows[i].SetActive(true);
                 break;
             }
         }
     }
 }

Script where I try to call the method FIRE from the previous one:

 public class Player_ClickToMove : MonoBehaviour
 {
     public Projectile projectileScript;
 
     public GameObject target;
 
     public GameObject arrowTest;
     public Transform arrowTargetTest;
 
     void Awake ()
     {
         projectileScript = GetComponent<Projectile>();  
     }
 
             if (Input.GetKeyDown(KeyCode.Z))
             {
                 projectileScript.GetComponent<Projectile>().Fire();
                 Debug.Log("Shooted");
             }
         }
     }
