title: Error "failed to load resource (map)" when using cdnjs
body: <p>I'm using some files from CDNJS:</p>
  <pre><code>&lt;link
    href=&quot;https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.2/css/bootstrap.min.css&quot;
    rel=&quot;stylesheet&quot;
  /&gt;
  &lt;link
    href=&quot;https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.14.0/css/all.min.css&quot;
    rel=&quot;stylesheet&quot;
    type=&quot;text/css&quot;
  /&gt; 
  [...] 
  &lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.slim.min.js&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.2/js/bootstrap.bundle.min.js&quot;&gt;&lt;/script&gt;
  </code></pre>
  <p>When using this files I get some errors in the console (safari/MacOS):</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 () (bootstrap.bundle.min.js.map, line 0)</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 () (bootstrap.min.css.map, line 0)</p>
  <p>I've found out maps are data about the files (is that correct?)
  Is it possible to fix this or is it a server error?</p>
