Look Rotation Viewing Vector is Zero

Hello there !

I have this little code there

 void OnTriggerStay2D (Collider2D other)
         {
             if (other.CompareTag ("Player")) {
                 target = other.transform;
                 target = GetComponent<Transform> ();
                 Aim ();
             }
         }
 
         void Aim()
             {
             Quaternion rotation = Quaternion.LookRotation
                 (target.transform.position - transform.position, transform.TransformDirection (Vector3.up));
             transform.rotation = new Quaternion (0, 0, rotation.z, rotation.w);
             }

So basicly the object should get the player and look at it but when it get in range i got the following error :

Look rotation viewing vector is zero

UnityEngine.Quaternion:LookRotation(Vector3, Vector3)

If anyone could help me to find the reason I would be very thankfull !

Have a good night / day! :)

EDIT : I forgot to mention that target is declared before as a private Transform.
