Heya, I want to stop a function node from executing its code if a payload is f.e. not a number. Is there anything like "node.stop" or "node.break"? I can't filter this in a node beforehand because there are more messages from other MQTT devices are going into. Thank you in advance.

Returning null does exactly that. Nothing is passed on. That is the recommended method. if ( isNaN(msg.payload)) { return null; }

Look for Q-gate in the library! [Opera Snapshot_2021-01-09_094629_discourse.nodered.org]

@ghayne thank you, but I think for just this "small feature" I don't wanna add a new package/plugin. If nothing is available for just "stopping" a function node from executing its code I will return a message with just "null". Thougth there would be an "recommended" way then doing this
