Good evening everyone, please if someone could tell me why I can't do the simple example of turning on a led connected to GPIO17, when I click on the inject, the led doesn't turn on, however the console indicates the event and text.

12 Sep 18:53:19 - [warn] [rpi-gpio out:LED] Invalid input: 1726185199649

I've already restarted the node red several times, I even tried the GPIO17 with a simple turn on routine as well and it works.

I appreciate your support in advance.

Note: I'm a Spanish speaker and I'm using Google Translate.

You are injecting a timestamp.

It should be a 0 or 1
