title: iframe with local html on React or Angular
body: <p><strong>I'm trying to show a local html file in an iframe.</strong>
  In both Angular and React, It works on development mode, <strong>but on production</strong> (AWS Amplify) <strong>I get the error &quot;cannot match any routes&quot;.</strong></p>
  <p>I tried all the answers on previous similar questions but no solution for me.
  I tried many sorts of locations( in src, in public, creating assets folder etc ).
  I tried many sorts of address syntax such as:</p>
  <pre><code>&lt;iframe src=&quot;address.html&quot;&gt;&lt;/iframe&gt;
  &lt;iframe src=&quot;./address.html&quot;&gt;&lt;/iframe&gt;
  &lt;iframe src=&quot;../address.html&quot;&gt;&lt;/iframe&gt;
  &lt;iframe src=&quot;./assets/address.html&quot;&gt;&lt;/iframe&gt;
  &lt;iframe src=&quot;../assets/address.html&quot;&gt;&lt;/iframe&gt;
  &lt;iframe src={process.env.BASE_URL + &quot;/assets/address.html&quot;}&gt;&lt;/iframe&gt;
  &lt;iframe src=&quot;https://awsAmplifyAddress.com/assets/address.html&quot;&gt;&lt;/iframe&gt;
  </code></pre>
  <p>etc...</p>
  <p><strong>Help...</strong></p>
