    Am I doing something wrong with the server for https://github.com/adamvr/MQTT.js? I see client.id come in fine. Everything else comes in as undefined; I verified the MQTT client’s info with another broker using 3.1 user/pass, so I know the issue is not there.clients = { }server = mqtt.createServer (client) =>console.log ‘Broker:mqtt:createServer’# Catch when client connectsclient.on ‘connect’, (packet) =>console.log ‘Broker:connect’client.connackreturnCode: 0client.id = packet.clientconsol
