Join does not trigger tasker event

[Tina Gamabit]

Hi,

I use tasker version 6.5.1-beta, and I call this from browser:

https://joinjoaomgcd.appspot.com/_ah/api/messaging/v1/sendPush?apikey=HHHH&deviceId=HHH&title=calltrigger&text=+123456

But all I get on my Android device is Join notice with correct text, but the event does not trigger:

In Tasker, I have:

Event: Join Received Push -> TextFilter: calltrigger.

Task: Call -> Number -> %JoinText

(if I try this event in Tasker, it works)

What else am I missing?

Thank you
