Parent value string contains invalid character

Thank you again! My issue now is it’s not showing anything at all. Is there something I’m missing?

New code:

<iframe
  var parent = ['plus.destructomc.com', 'sites.google.com', 'www.gstatic.com', window.location.host];
  console.log(parent);
  document.getElementById('target_frame').setAttribute('src', document.getElementById('target_frame').getAttribute('src') + '&parent=' + parent.join('&parent='));

  var options = {
    width: 720,
    height: 1280,
    channel: "destructolive",
    allowfullscreen: true,
    layout: "video-with-chat",
    muted: true,
    parent
  };
  var player = new Twitch.Embed("test", options);
</iframe>
