I have a problem inflicting damage to my enemies... It works when using it without an array but as soon as I I do put them in it gives me a "MissingMethodExpection"... Here is the code

//This is damage function

[SerializeField] private float maxHealth, knockBackSpeedX, knockBackSpeedY, knockBackDuration, knockBackDeathSpeedX, knockBackDeathSpeedY, deathTorque;

 [SerializeField]
 private bool applyKnockBack;
 [SerializeField]
 private GameObject hitParticle;
     

 private float
     currentHealth,
     knockBackStart;

 private int playerFacingDirection;

 private bool 
     playerOnLeft,
     knockBack;

 
 private PlayerMovement pc;

 private GameObject
     aliveGO,
     brokenTopGO,
     brokenBotGO;

 private Rigidbody2D
     rbAlive,
     rbBrokenTop,
     rbBrokenBot;

 private Animator aliveAnim;

 private void Start()
 {
     currentHealth = maxHealth;

     pc = GameObject.Find("Player").GetComponent<PlayerMovement>();

     aliveGO = transform.Find("Alive").gameObject;
     brokenTopGO = transform.Find("Broken Top").gameObject;
     brokenBotGO = transform.Find("Broken Bottom").gameObject;

     aliveAnim = aliveGO.GetComponent<Animator>();
     rbAlive = aliveGO.GetComponent<Rigidbody2D>();
     rbBrokenTop = brokenTopGO.GetComponent<Rigidbody2D>();
     rbBrokenBot = brokenBotGO.GetComponent<Rigidbody2D>();

     
     aliveGO.SetActive(true);
     brokenTopGO.SetActive(false);
     brokenBotGO.SetActive(false);
    
 }

 private void Update()
 {
     CheckKnockBack();
 }

 public void Damage(float details)
 {
     currentHealth -= details;

     if (details < aliveGO.transform.position.x)
     {
         playerFacingDirection = 1;
     }
     else
     {
         playerFacingDirection = -1;
     }

     Instantiate(hitParticle, aliveGO.transform.position, Quaternion.Euler(0.0f, 0.0f, Random.Range(0.0f, 360.0f)));

     if (playerFacingDirection == 1)
     {
         playerOnLeft = true;
     }
     else
     {
         playerOnLeft = false;
     }

     aliveAnim.SetBool("playerOnLeft", playerOnLeft);
     aliveAnim.SetTrigger("damage");

     if (applyKnockBack && currentHealth > 0.0f)
     {
         KnockBack();
     }

     if (currentHealth <= 0.0f)
     {
         Die();
     }
     
 }

 private void KnockBack()
 {
     knockBack = true;
     knockBackStart = Time.time;
     rbAlive.velocity = new Vector2(knockBackSpeedX * playerFacingDirection, knockBackSpeedY);
 }

 private void CheckKnockBack()
 {
     if (Time.time >= knockBackStart + knockBackDuration && knockBack)
     {
         knockBack = false;
         rbAlive.velocity = new Vector2(0.0f, rbAlive.velocity.y);
     }
 }

 private void Die()
 {
     aliveGO.SetActive(false);
     brokenTopGO.SetActive(true);
     brokenBotGO.SetActive(true);

     brokenTopGO.transform.position = aliveGO.transform.position;
     brokenBotGO.transform.position = aliveGO.transform.position;

     rbBrokenBot.velocity = new Vector2(knockBackSpeedX * playerFacingDirection, knockBackSpeedY);
     rbBrokenTop.velocity = new Vector2(knockBackDeathSpeedX * playerFacingDirection, knockBackDeathSpeedY);

     rbBrokenTop.AddTorque(deathTorque * -playerFacingDirection, ForceMode2D.Impulse);

     
 }

//This is in combat damage script

private void CheckAttackHitBox() { Collider2D[] dectectedObjects = Physics2D.OverlapCircleAll(attack1HitBoxPos.position, attack1Radius, whatIsDamagable);

     foreach (Collider2D collider in dectectedObjects)
     {
         collider.transform.parent.SendMessageUpwards("Damage", attack1Damage);
         //Instantiate hit particle
     }
 }
