I got my commandID from here:

reaper is recieving the following signal
"/action/_RSd0e44f6d7708e318e09ab4bb4b78aa67765abbea"
I can see it in listening to it in "control surface settings" so it is recieving the signal.
Why is this not working.
for the record when I send "/action/40044" it works.. but not my custom action.... why?
