Since i have created my pega application in my personal system, i have disabled SSL. Is that the problem?
I have listed out a bunch of questions here. Also, as you say if using PE is the problem, i am interested in understanding the reason behind it. It would make sense if i am trying to contact Pega from Robotic Automation. Instead i am trying to call a Robotic automation component (Robot Activity) from Pega. This should work fine, ideally.
Also, please make sure that you are using Pega 7.2.2 and that the name that you provided for the "Automation" is the ActivityName located in the RobotActivity properties and not the actual name of the automation.
If you are still having issues with this I would recommend that you open an SR.
