There is something wrong with the code

var image = new Image();
image.src = canvas.toDataURL("image/png");
var link = document.createElement('a');
link.href = image;
link.download = 'Download.png';
document.body.appendChild(link);
link.click();

      

        
        
        
      

    

When I use this script it returns me a download error

(File not found)

      

        
        
        
      

    

Why?
