**Description**  
I am using websdk with client view. Zoom meeting is started by host using zoom mac desktop client. Attendees are joining using zoom websdk. Zoom host creates 2 breakout rooms and gives option to attendees to join the breakout room. When the attendee chooses and joins the breakout room there is a crash.

**Browser Console Error**  
**react-dom.development.js?ad67:289 Uncaught TypeError: Cannot read properties of undefined (reading ‘call’)**
