Controlling an Animator Toggle Parameter

I followed a tutorial I found (a couple actually) and came up with a simple way to control a door animator which has been hooked up to control keyframe animations embedded into the model.

This works fine when I manually change the Toggle Parameters Open/Close in the Animator window, but when attempting to do the same programatically (by triggering ToggleTrigger, with or without arguments) nothing changes.

I have attached the script below the image of my Animator graph.

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

public class BulkheadDoorControllerScript : MonoBehaviour
{
    public Animator animator;

    //public variable
    public bool isOpen;

    //set the animator based on input value currentPosition
    public void ToggleTrigger(bool currentPosition)
    {
        if (currentPosition)
        {
            animator.SetTrigger("Open");
        }
        else
        {
            animator.SetTrigger("Close");
        }
    }

    //override method sets the animator, then toggles the public bool
    public void ToggleTrigger()
    {
        isOpen = !isOpen;
        ToggleTrigger(isOpen);
    }

}

I drag the Animator component onto the animator variable slot in the Inspector, then when triggering the change, seemingly nothing happens, in the Game, Scene or Animator windows.

Can anyone see what exactly it is that I am doing wrong?

I have the same issue some time ago,
try to change to the bool system: same thing, but just a bool

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
 
    public class BulkheadDoorControllerScript : MonoBehaviour
    {
        public Animator animator;
 
        //public variable
        public bool isOpen;
 
        //set the animator based on input value currentPosition
        public void ToggleTrigger(bool currentPosition)
        {
            isOpen = currentPosition;
            animator.SetBool("Open", currentPosition);
        }

        public void ToggleTrigger()
        {
            isOpen = !isOpen;
            animator.SetBool("Open", isOpen);
        }
 
    }
