Unity trigger method does nothing

I have the following script on my object:

public class PlayMyCube : MonoBehaviour
{
    [SerializeField] private Animator myAnimationController;

    private void onTriggerEnter(Collider other) {
        if (other.CompareTag("Player")) {
            myAnimationController.SetBool("playSpin2", true);
        }
    } 

    private void OnTriggerExit(Collider other) {
        if (other.CompareTag("Player")) {
            myAnimationController.SetBool("playSpin2", false);
        }
    }
}

When the player character is inside the first cube's trigger, my second cube should play a spinning animation. When they leave, the second cube should stop.

But what happens in the game now is, when the character runs into the trigger, it does nothing.

I have configured my trigger object like this:

I have configured the object that should spin like this:

And configured the Animation Controller like this:

And configured my Player object like this:

What can I do to make this animation play when the player is inside the trigger?
