### My code

```html
<html>
  <head>
    <!-- Load TensorFlow.js -->
    <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script>
    <!-- Load Posenet -->
    <script src="https://cdn.jsdelivr.net/npm/@tensorflow-models/posenet"></script>
 </head>

  <body>
    <img id='cat' src='./pose/images/aa_085.jpg'/>
  </body>
  <!-- Place your code in the script tag below. You can also use an external .js file -->
  <script>
    var flipHorizontal = false;

    var imageElement = document.getElementById('cat');

    posenet.load().then(function(net) {
      const pose = net.estimateSinglePose(imageElement, {
        flipHorizontal: true
      });
      return pose;
    }).then(function(pose){
      console.log(pose);
    })
  </script>
</html>

```

I rarely use HTML and JavaScript and almost forget the most fundamentals. What is the error?
