the error message:
29 Jul 10:34:31 - [info] [mqtt-broker:Orange] Connected to broker: mqtt://
(node:8652) UnhandledPromiseRejectionWarning: # (node:8652) UnhandledPromiseRejectionWarning: Unhandled promise rejection.
This error originated either by throwing insi de of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Not sure what the question has to do with the thread title. What node are you using to connect to the orange mqtt broker?
Note that it is a warning rather than an error.
Also show us the startup log that you see if you start node-red in a terminal.
