Crash on breakout-room joining

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’)
