NavMeshAgent nextPosition is not updating

I set the destination when the player clicks on the environment. NavMesh is baked. Here is the actual movement of agent.

 using UnityEngine;
 using UnityEngine.AI;
 using System.Collections;
 
 public class AnimateMovement : MonoBehaviour {
 
     public Animator anim;
     public Transform player;
     public NavMeshAgent agent;
     Vector2 smoothDeltaPosition = Vector2.zero;
     Vector2 velocity = Vector2.zero;
     public bool isMoving = true;
 
     void Start()
     {
         //agent = GetComponent<NavMeshAgent>();
         agent.updatePosition = false;
     }
 
     void Update()
     {
         
         Debug.Log(agent.nextPosition + " " + player.position);
         Vector3 worldDeltaPosition = agent.nextPosition - player.position;
 
         // Map 'worldDeltaPosition' to local space
         float dx = Vector3.Dot(player.right, worldDeltaPosition);
         float dy = Vector3.Dot(player.forward, worldDeltaPosition);
         Vector2 deltaPosition = new Vector2(dx, dy);
 
         // Low-pass filter the deltaMove
         float smooth = Mathf.Min(1.0f, Time.deltaTime / 0.15f);
         smoothDeltaPosition = Vector2.Lerp(smoothDeltaPosition, deltaPosition, smooth);
 
         // Update velocity if delta time is safe
         if (Time.deltaTime > 1e-5f)
             velocity = smoothDeltaPosition / Time.deltaTime;
         Debug.DrawLine(deltaPosition, smoothDeltaPosition, Color.blue);
         isMoving = velocity.magnitude > 0.5f && agent.remainingDistance > agent.radius;
 
         // Update animation parameters
         anim.SetBool("Move", isMoving);
         anim.SetFloat("velx", velocity.x);
         anim.SetFloat("vely", velocity.y);
         //Debug.Log(worldDeltaPosition);
     }
 
     void OnAnimatorMove()
     {
         // You'd have to set this value yourself, lots of ways to do that with the animator.
 
 
         if (isMoving)
         {
             agent.velocity = anim.deltaPosition / Time.deltaTime;
             agent.speed = anim.deltaPosition.magnitude / Time.deltaTime;
         }
         else
         {
             agent.velocity = Vector3.zero;
             agent.speed = 0.00001f; // Setting it to 0 can cause agent to do weird stuff
         }
         // Update postion to agent position
         //Debug.Log("Moving");
         player.position = agent.nextPosition;
     }
 }

The boolean agent.nextPosition stays the same whenever I set the destination like here:

  RaycastHit hit;
             if (Physics.Raycast(cam.ScreenPointToRay(Input.mousePosition), out hit, Mathf.Infinity))
             {                    
                     if (hit.collider.gameObject.layer == groundLayer)
                     {
                         if (Input.GetMouseButtonUp(0))
                         {
                             currentNode.CurrentNode = false;
                             currentNode = nm.getNearestNode(hit.transform.position);
                             currentNode.CurrentNode = true;
                             //agent.nextPosition = currentNode.Position;
                             agent.SetDestination(currentNode.Position);
                             Debug.Log(agent.destination);
                         }
 }
 }

Here is the image. The red line shows the path is set, but the player is not moving.
