Do you mean “automation trigger” instead of “action”?
What is not working? Is the automation not triggering? Try removing the event_label and see if it works then (even if it triggers too much). With strings like that, it’s possible there are unusual space characters that are preventing an exact match.
I don’t think event_label is a string based on your first picture as well as multiple examples in posts on this forum. Try removing the quotes from “Keypad unlock operation”.
If that doesn’t work, try Troon’s suggestion and remove the event_label line. After testing if it works without it, you can then add in
type: 6
event: 6
to narrow down the triggers to that specific event.
