title: How can I fix the "DevTools failed to load SourceMap: Could not load content" error when adding a JavaScript library?
body: <h3>My code</h3>
  <pre class="lang-html prettyprint-override"><code>&lt;html&gt;
    &lt;head&gt;
      &lt;!-- Load TensorFlow.js --&gt;
      &lt;script src=&quot;https://cdn.jsdelivr.net/npm/@tensorflow/tfjs&quot;&gt;&lt;/script&gt;
      &lt;!-- Load Posenet --&gt;
      &lt;script src=&quot;https://cdn.jsdelivr.net/npm/@tensorflow-models/posenet&quot;&gt;&lt;/script&gt;
   &lt;/head&gt;
  
    &lt;body&gt;
      &lt;img id='cat' src='./pose/images/aa_085.jpg'/&gt;
    &lt;/body&gt;
    &lt;!-- Place your code in the script tag below. You can also use an external .js file --&gt;
    &lt;script&gt;
      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);
      })
    &lt;/script&gt;
  &lt;/html&gt;
  </code></pre>
  <p>I rarely use HTML and JavaScript and almost forget the most fundamentals. What is the error?</p>
