Epic is not able to find the associated parent feature.......why?

Pratiksha Ananta Kumbharkar

I am uploading this script in the post function of epic(on the create transition....the very first transition in the workflow)......and we are using plugin "exocet" which directly provides button "create epic" on feature issue to create epic.....Epic is not able to find the associated parent......why?
