title: Pdfmake Uncaught invalid image error even with correctly url
body: <p>When I try to download PDF file with image generated by pdfmake I got:</p>
  
  <pre><code> Uncaught invalid image, images dictionary should contain dataURL entries (or local file paths in node.js)
  </code></pre>
  
  <p>I have visited playground on their <a href="http://pdfmake.org/playground.html" rel="nofollow noreferrer">website</a> but I got there the same error.</p>
  
  <p>Here I paste the <a href="https://pastebin.com/j9CrMFMg" rel="nofollow noreferrer">example</a> url to image generated by my server. It works fine as you can see (paste it to the browser url). </p>
  
  <p>Finally I posted code:</p>
  
  <pre><code> pdfMake.createPdf({
      content:[{image: 'url from paste bin here'}]
    }).download();
  </code></pre>
  
  <p>Honestly I have ran out of ideas. </p>
