Failed to unsubscribe from triggers: ${errorMessage}

Error message

Failed to unsubscribe from triggers: ${errorMessage}

What it means

Catch-all wrapper for failures in triggerUnsubscribe; the underlying message is appended. Usually wraps error 407 (client not initialized) or a pusher-js unsubscribe exception on a dead connection.

Solutions

1. Check the appended underlying message
2. Skip unsubscribe when the client is uninitialized or the connection is already closed (idempotent teardown)
3. Wrap teardown in a best-effort try/catch that logs rather than throws during shutdown

Example fix

// before
PusherUtils.triggerUnsubscribe(clientId);

// after
try {
  PusherUtils.triggerUnsubscribe(clientId);
} catch {
  // best-effort teardown; connection already gone
}

if (PusherUtils.pusherClient) {
  PusherUtils.triggerUnsubscribe(clientId);
}

try {
  PusherUtils.triggerUnsubscribe(clientId);
} catch {
  // already disconnected; safe to ignore during shutdown
}

When it happens

Trigger: Calling triggerUnsubscribe when the client is missing (407) or when the underlying websocket has already disconnected and unsubscribe throws.

Common situations: Cleanup paths racing with disconnects; teardown during process shutdown after the connection dropped.
