Try replacing that files content with the code below

Changes:

  1. Ensure all promise calls have a .catch block & that node.error() is called upon error (so a use can catch errors with the catch node
  2. Add "connect" msg support. This way, you can send a msg with a topic of "connect" to change (or reconnect) at runtime (pass the username and password in the msg or msg.payload

        node.on('input', function (msg) {
