Payload message object key with a space? Got a python script that sends MQTT data and one of the keys in the resulting JavaScript object (via JSON) has spaces in the key string.

So, "System Up TIme: XXXXX" versus "SystemUpTime: XXXXX" for example. Space are legit apparently in key names, and JavaScript objects, but how does one qualify such in a change node?

msg.payload.System Up Time  
msg.payload."System Up Time"  
msg.payload["System Up Time"]

None of the above work?

Apparently you can do msg.payload["System Up Time"] in a functional node.

In a Change node, assuming you have set it to `msg` type, you can enter `payload["System Up Time"]`

You use [copy path] button from the debug sidebar then paste it into the change node textbox
