I have create a maze, I want after clicking I want to draw a path line but no matter where I click everytime Navmesh.calculatepath returns false value.

Here is my code.

    void Update()
{
    if (Input.GetMouseButtonDown(0)){
        StartCoroutine(Makepath());
    }
}

private IEnumerator Makepath(){

        Ray Moveposition = Camera.main.ScreenPointToRay(Input.mousePosition);
        if (Physics.Raycast(Moveposition, out var hitposition))
        {
            Vector3 agentpos = agent.transform.position;
            NavMeshPath path = new NavMeshPath();

            agent.SetDestination(hitposition.point);

            NavMesh.CalculatePath(agentpos, hitposition.point, NavMesh.AllAreas, path); 
            Debug.Log(path.corners.length + "<<<<Path.corner length");
            Debug.Log(agentpos + "<<<agentpos");
            Debug.Log(hitposition.point + "<<<hitposition.point");
    }
    yield return null;
}

and here is output I found in console
