Start with the reported stack in node_modules/ws/lib/Receiver.js, especially Receiver.controlMessage and its callers in Receiver.js and WebSocket.js. Determine what produces status code 12592 for a server using the mqtt protocol, then reproduce the failure and document a verified fix or regression coverage; the issue does not specify expected behavior.
