Hi unless I'm missing something I think lines 151++ should be something like this otherwise the IMG tag is missing

  let FacebookPixelNS = document.createElement('noscript');
  let FacebookPixel = document.createElement('img');
  FacebookPixel.setAttribute('height', `1`);
  FacebookPixel.setAttribute('width', `1`);
  FacebookPixel.setAttribute('style', `display:none`);
  FacebookPixel.setAttribute('src', `https://www.facebook.com/tr?id=${this.tracking.FacebookPixelCode}&ev=PageView&noscript=1`);
  FacebookPixelNS.appendChild(FacebookPixel);
  document.head.appendChild(FacebookPixelNS);

Best
Martin
