What it means

Solutions

1. Start a new livechat session / reopen the chat to obtain a new open room before sending.
2. Inspect room.open before posting; if closed, prompt the user to begin a new conversation.
3. If reopening is supported in your flow, re-open the existing room and retry.

Example fix

// before
POST /livechat/message { token, rid, msg } // room-closed

// after
const room = await findRoom(token, rid);
if (room && !room.open) { /* start new conversation / reopen chat */ }
POST /livechat/message { token, rid, msg }

const room = await findRoom(token, rid);
if (room && !room.open) {
  // start a new conversation / reopen, then retry
  throw new Error('room is closed');
}
// safe to POST /livechat/message

const isRoomOpen = (room: IOmnichannelRoom | null): room is IOmnichannelRoom =>
  !!room && room.open === true;

try { await sendMessage({ token, rid, msg }); }
catch (e) { if (e instanceof Error && e.message === 'room-closed') { /* prompt new conversation */ } else throw e; }

When it happens

Trigger: Sending a message to a livechat room whose `open` flag is false.

Common situations: Chat ended by agent or visitor; auto-close after inactivity timeout; attempting to reply after the session was closed.
