Local variable gets null after assigning.

Hey,

I have a network object with a class attached named Hook.cs, and another network object with Player.cs class attached to it.

To be clear hook is like a bullet and the player is the one who shoots it.

now whenever my player collided with my hook, Player.cs calls a method on Hook.cs :

private void OnTriggerEnter(Collider incomingHook)
{
    if (incomingHook.gameObject.tag == "Hook")
        {
            Debug.Log("hook collided");
            incomingHook.gameObject.transform.parent.GetComponent<NetworkOnHook>().HookCatch(Object.gameObject,Object.InputAuthority);
            HandleAfterHook();
        }
}

and this is the method that has been called:

public void HookCatch(GameObject plr, PlayerRef playerRef)
{
    if (Object.HasInputAuthority)
    {
        if (Runner.TryGetPlayerObject(playerRef, out var playerObj))
        {
            hookedPlayerController = playerObj.GetComponent<NetworkPlayerController>();
            Debug.Log(hookedPlayerController.playerID);
        }
    }
}

and as you can see, my variable hookedPlayerController is not null at the moment it has been initialized, but when I check that on my fixedUpdateNetwork method or Update or other methods, it's null.

I wonder what the problem is and I appreciate a tip or a guide.
