How do you get iTween to properly implement PutOnPath command?

I am trying to use iTween to get a gameObject to follow a path and end up in a specific location. I keep getting an error which is "IndexOutOfRangeException: Array index is out of range."

Any help on this would be greatly appreciated! Here is my code

public class MosquitoCamPath : MonoBehaviour {

 float percentsPerSecond = 0.02f;
 float currentPathPercent = 0.0f;
 public Vector3[] path;
 // Use this for initialization
 void Start () {


     
     Vector3[] path = new Vector3[5];
     path[0] = new Vector3(5, 45, 5);
     path[1] = new Vector3(8, 30, 16);
     path[2] = new Vector3(15, 20, 20);
     path[3] = new Vector3(8, 15, 22);
     path[4] = GameObject.Find("Mosquito Model(Clone)").GetComponent<Pathing>().loc;

    

 }
 
 // Update is called once per frame
 void Update () {

     currentPathPercent += percentsPerSecond * Time.deltaTime;

     iTween.PutOnPath(gameObject, path, currentPathPercent);
     iTween.LookTo(gameObject, GameObject.Find("Mosquito Model(Clone)").GetComponent<Pathing>().loc, 15);
 }

}
