Bones rotation from script with LateUpdate

Unity Engine
1

So i have an AI that have some animations but i also need the head to rotate to player direction but its not working neither in late update . Here is the Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AI_chasing : MonoBehaviour {
    static public Transform player;
    [SerializeField]private float speed;
    [SerializeField]private float movespeed;
    [SerializeField]private Transform head;
    private  Animator anim;
    // Use this for initialization
    void Start () {
        player = GameObject.Find ("FPSController").transform;
        anim=this.GetComponent<Animator>();
    }
   
    // Update is called once per frame
    void Update () {
        Vector3 direction = player.position - this.transform.position;
        direction.y = 0;
        //    float angle = Vector3.Angle (direction, head.forward);
        if (Vector3.Distance (player.position, this.transform.position) < 10) {
            this.transform.rotation = Quaternion.Slerp (this.transform.rotation, Quaternion.LookRotation (direction), speed * Time.deltaTime);
            anim.SetBool ("is_idle", false);
            if (direction.magnitude > 1.3f) {
                this.transform.Translate (0, 0, movespeed * Time.deltaTime);
                anim.SetBool ("is_running", true);
                anim.SetBool ("is_attacking", false);
            } else {
                anim.SetBool ("is_attacking", true);
                anim.SetBool ("is_running", false);
            }
        } else {
            anim.SetBool ("is_idle", true);
            anim.SetBool ("is_running", false);
            anim.SetBool ("is_attacking", false);
        }
    }
    void LateUpdate()
    {
        Vector3 direction2 = player.position - head.transform.position;
        head.transform.rotation = Quaternion.Slerp (head.transform.rotation, Quaternion.LookRotation (direction2), speed * Time.deltaTime);
    }
}

I don’t know why, please help. :L

any updates with it ?

It looks like the variable “head” is not being assigned a value…
If it would be filled with the right Transform, you need to use head.rotation instead of head.transform.rotation. (same with position)
Hope it helps.
