Hi,
What you have there looks syntactically excellent... I can’t find anything wrong.
This intrigued me, so I tried a config on my Revo system. It worked fine with a call using startId. Then I looked through all the configs there, and none had a startId. So I tried using a startId in the config I was testing (instead of in the call), and I got no output at all. So my guess would be that for some reason startId doesn’t work in that spot, maybe. Would probably require some digging to find out for sure.
Does your config work if you included startId in your call?
Cheers, Dave
