Button Controller 5.1 [Error] Failed trigger: push 1

So I have a virtual switch and a RM5.1 rule triggered to push a button on a virtual button device. this appears to work.

I have a Button Controller 5.1 for that virtual button, with custom actions to drive the LED of the Zooz Switch (Fan).

It gets to the Button 5.1 rule for that button (1) but nothing happens, the log emits
[Error] Failed trigger: push 1

I assumed the button controller sub rules are triggered by the button press. What am I missing?

Here's the log snippet

A failed trigger

This is the button controller: app is 239, button rule is 240

This is the Button 5.1 sub rule for button 1 (240)

Ugh, the perils of late night Rule Machining. I did led commands in dyslexic. setLEDMode is for on/off. and setLED is for color. I reversed the commands and it works.
