Scriptrunner - Clone subtask to a linked ticket from the parent ticket

[Johan Lourens]

Hi there,

I'm very new at Scriptrunner!

On a certain transition, I'm trying to clone and link a subtask from project B to an existing linked ticket on project A. Below is what I've been able to put together from my research. It works when I point it to a ticket in project B, but it does nothing when I point to a ticket in project A. The end goal is to have an exact clone of the parent and subtasks in projects A & B that are linked to each other.
