50377: Can't update conversation as it's in final closed state
PROGRAMMABLE CHAT
ERROR
Conversation state is 'closed' so it can't be used for chatting anymore.
- Conversation state is set manually or by timer to 'closed' which means that conversation can't be updated anymore.
- Create new conversation in 'active' state without 'TimeToClosed' or with some big duration to avoid unexpected movement to 'closed' state.
