Cannot read properties of null (reading 'init')

Bug Attempting to use the asciinema player in both Chrome and Firefox results in a properties of null error, or a type error.

To Reproduce

Install asciinema player
Open in browser
Click play button
See error

Expected behavior Player plays recording when play button is clicked

Screenshots Chrome: chrome Firefox: firefox

Versions:

OS: Windows 11 Enterprise Version 21H2 OS Build 22000.246
Browser: Firefox 118.0.1 and Chrome Version 117.0.5938.132
asciinema player: 3.6.1

Additional context I have added CSP headers to both my html and NGINX config

The html:

<!DOCTYPE html>
<html>
<head>
  <meta http-equiv="Content-Security-Policy" content="default-src 'self' http: https: ws: wss: data: blob: 'unsafe-inline' 'unsafe-eval' 'wasm-unsafe-eval'">

  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      'neofetch.cast',
      document.getElementById('player'),
      { cols: 203, rows: 62 }
    );
  </script>
</body>
</html>

NGINX header:

add_header Content-Security-Policy "script-src 'self' 'unsafe-inline' 'wasm-unsafe-eval';";
