Illegal view ID When trying to destroy Instantiated prefab

public float enemySpeed;
public float hp = 10f;
PhotonView PV;

private void Awake()
{
Invoke("Delete", 7);
PV = GetComponent<PhotonView>();
}
private void FixedUpdate()
{
transform.Translate(0, -enemySpeed * Time.deltaTime, 0);
if (hp <= 0) PV.RPC("DestroyRPC", RpcTarget.All, transform.gameObject);
}
private void OnTriggerEnter2D(Collider2D collision)
{
PV.RPC("RPC_Destroy", RpcTarget.All);
hp = hp - 1;
}

[PunRPC]
void RPC_Destroy()
{
print("test");
}
void Delete()
{
Destroy(gameObject);
}

I am trying to Destroy a gameObject, but I can't seem to acces the PhotonView. Any ideas?
