How to identify an error

I rcv following debug message (red) since a few hours without changing anything on this node or flow:

created staircase-timer with config {"id":"be5786f2f56b6c05","type":"staircase-timer","z":"15383e6849c86130","name":"Treppenhaus","timeout":"45","onPayload":"true","onPayloadType":"bool","offPayload":"false","offPayloadType":"bool","renewable":false,"communicative":"","x":830,"y":440,"wires":[["c28d9678f6ad3265"]]}

can anybody explain me this message and how to disable it.

regards Erwin

Is this a custom node you are developing? Or an existing contrib node that you installed?

It is a contrib node - staircasetimer
