Trouble understanding json for notifications

Im trying to set up a persistent notification to tell me why something happened.
The message object looks like this:

and im trying to capture the blindctrl reason in a notification like this:

But all I get is the first part of the text, (Triggered by node red) and nothing else, no errors.
What am I doing wrong?

imo payload of the message is 0 (zero). So blindCtrl cannot be its attribute

thanks for the pointer, dropping “payload” from the front worked :slight_smile:
