The protocol will stop running due to the error 'Property Call already exists'. I have attached a screenshot of the error message. I can see from the screen that there is a property named 'Call', but I'm not sure why it is running into error in the unpivot component. Also, the same protocol was working as usual before the upgrade to Pipeline Pilot 2018. Feel free to let me know if i was unclear. I will appreciate any inputs. Thank you.
