Animation play error. No animation attached.

I've been trying to play the animation I created inside of unity. I've added the animation to an empty gameobject called "SwingAnimation"(It's no longer empty). (I created the animation using a cube which I later removed to add a sword.)

The animation is working since its looping every time I test it out.

This is the code which I've been trying to play the animation with:

swing.js Attached to the Player.

 function Update () {
 
     if (Input.GetButton ("Fire1")) {
         
         GameObject.Find("SwingAnimation").animation.Play("swing");
 
     }
 
 }

I have also tried attaching the script directly on the gameobject containing the animation directly with:

function Update () {

 animation.Play();

}

But all I get is: There is no 'Animation' attached to the "SwingAnimation" game object, but a script is trying to access it.

I'm just scratching my head wondering how this can be? There is clearly an animation attached to the gameobject SwingAnimation. What am I doing wrong and how can I fix this?

Thank you in advance for any help you can provide and I apologize if I re-post the question on the matter but I could not find any solution for my problem amongst them. // N0tiC
