Compare CDN vs github of "xrextras"

I’m getting an error in the show video preview section (IOS 17)
Demo: Character Camera | 8th Wall Playground | 8th Wall
Using: https://cdn.8thwall.com/web/xrextras/xrextras.js NO BUG
Using: web/xrextras/src/mediarecorder/media-preview.js at master · 8thwall/web · GitHub NO SHOW PREVIEW

  • CDN:
    image
  • GitHub:
    image

I’m wondering what the difference is between the two versions.
