The latest mock server posted in Zoom RTMS Announcements on Feb 27 (zip md5 = bc11e595e893872c14526431fad67b25) is slightly broken at the moment. When starting a video call, the test client errors out with a 404 when making a websocket request to the media server. As far as I can tell, the media server’s media endpoint is not listening for any upgrade requests. Instead, the media server’s handshake endpoint is listening to and handling upgrade requests for media.
Until a fix is posted, here’s a patch folks can apply to server/handlers/signalingHandler.js in the meantime:
