prlanzarin 71f958ca47 fix(bbb-html5): crash due to undefined metadataProp access 
A client crash may happen if either the Meeting collection or the
document's metadataProp attribute are undefined whenever the
getFromMeetingSettings util is called to fetch metadata.
It's debatable whether anything is working in the client if the
documents being accessed here are unavailable, but it'll still be logged
and might bork an ongoing reconnect.

Use optional chaining + nullish coalescing to avoid causing TypeErrors
in those situations while also returning default metadata values
properly.

BigBlueButton

BigBlueButton is an open source web conferencing system.

BigBlueButton supports real-time sharing of audio, video, slides (with whiteboard controls), chat, and the screen. Instructors can engage remote students with polling, emojis, multi-user whiteboard, and breakout rooms.

Presenters can record and playback content for later sharing with others.

We designed BigBlueButton for online learning, (though it can be used for many other applications as well). The educational use cases for BigBlueButton are

  • Online tutoring (one-to-one)
  • Flipped classrooms (recording content ahead of your session)
  • Group collaboration (many-to-many)
  • Online classes (one-to-many)

You can install on a Ubuntu 20.04 64-bit server. We provide bbb-install.sh to let you have a server up and running within 30 minutes (or your money back 😉).

For full technical documentation BigBlueButton -- including architecture, features, API, and GreenLight (the default front-end) -- see https://docs.bigbluebutton.org/.
