Question Animation.Play doesn't play animation

can someone help me figure out my why animation doesnt play?

here's my project. it's just a test animation

https://easyupload.io/nx0dl5

essentially i just have a cube running a timeline animation, and my code is using

Code (CSharp):

1. if (Input.GetKey("a")){ transform.GetComponent<Animator>().Play("test"); }

but the animation doesn't play except on the first run of the project.

ive attached the script to a hierarchy object as well...

I've disabled the Loop checkbox as well since I only want the Animation to play once for each press of "a"
