This problem is caused by
https://unpkg.com/react/umd/react.production.min.js
is dead and cannot be accessed.

My temporary solution is to use another CDN :

  • comment out
<!-- <meta name="8thwall:package" content="@react.react"> -->

<!-- <meta name="8thwall:package" content="@react.react-dom"> -->

<!-- <meta name="8thwall:package" content="@react.react-router-dom"> -->
  • Add new CDN
<script src="//cdn.jsdelivr.net/npm/react@latest/umd/react.production.min.js"></script>

<script src="//cdn.jsdelivr.net/npm/react-dom@latest/umd/react-dom.production.min.js"></script>

<script src="//cdn.jsdelivr.net/npm/react-router-dom@latest/umd/react-router-dom.min.js"></script>
