Hello & Thanks , I am getting this error: Uncaught TypeError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(HTMLImageElement or HTMLVideoElement or HTMLCanvasElement or ImageBitmap)' on this line: ctx.drawImage(cowpies[i], cowpies[i].x, cowpies[i].y, cowpies[i].width, cowpies[i].height); I got no error msg from the 'onload' . Haven't figured out what I am doing wrong . Pls , take a look .
