Meeting SDK Type and Version
Web, 3.5.2
Description
Zoom Meeting SDK for Web is integrated into a React application.
Webinar attendees using the app are unable to view webinar “Resources”.
When the “Resources” button is clicked, the resources panel opens but hangs on a loading spinner UI.
Error?
The above is accompanied the following errors logged to the browser console:

I’m also able to reproduce this issue using the simple Meeting SDK React sample.
Is this caused by a bug in the Zoom Meeting SDK for Web?
