[Uncaught exception: Cannot tween a null target.]

Good night guys!

 

I am trying to make an animation where the title of my draw are constantly changing color.

I am using this function to get the color randomly

function tweenToRandomColor(ctx) {
		TweenLite.to(ctx, 1, {colorProps:{fillStyle:"rgb(" + random(0,255) + "," + random(0,255) + "," + random(0,255) + ")"}, onUpdate:title, onComplete:tweenToRandomColor});
}

And here is the function that generates the random values

function random(min, max) {
  return (min + Math.random() * (max - min) + 0.5) | 0;
}

Here is the functions that ai changing color

function title(){
	var c = document.getElementById("acanvas").getContext("2d");
	c.font="600 35px verdana";
	c.fillText("SNAKES ON A PLANE",125,130);
	c.fill();
}

Here my Main();

function main() {
    var c2d = document.getElementById("acanvas").getContext("2d");
	capa(c2d);
	AllWindows(c2d);
	tweenToRandomColor(c2d);
}

 

I put all the code in this codepen link https://codepen.io/boladeberlin/pen/eKKNOy
