Saving canvas in PDF

p5.js Libraries
10

Here is a minimal example that is not working:

var sign = true;

function setup() {
  var myCanvas = createCanvas(400, 400, SVG);
  myCanvas.parent("myContainer");
  pdf = createPDF();
  pdf.beginRecord();
}

function draw() {
  fill(0, 0, 255);
  ellipse(width/2, height/2, width/2, height/2);
  if (sign) {
    pdf.save( {
    filename: 
      "ethercoil.pdf"
    }
    );
    sign = false;
  }
}

  <body>
  <h1>EtherCoil</h1>

  <div style = "text-align: center;"  id="myContainer"></div>


  </body>
</html>

Error is:


Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.

I am using PDE in P5 mode. I adapted the code from this.

Thanks for help.
