[stable35] fix(call): guard against a missing local state broadcaster when leaving a call - #19261
Merged
Conversation
…ng a call The "beforeLeaveCall" handler assumes that "beforeJoinCall" ran before it and left a broadcaster behind. The variable is null whenever the call was not joined in this page session, and it is set back to null after the first leave. leaveRoom() calls leaveCurrentCall() unconditionally, so leaving or switching a conversation reaches the handler either way and raises "Cannot read properties of null (reading 'destroy')". The exception is raised inside the promise chain of leaveCall(), so it aborts whatever the caller was doing, for example the switchto handling that moves participants to another conversation when a one-to-one conversation is extended into a group conversation.
