Naveen,
Without actually seeing your code, it’s hard to say what is being done wrong. However, based solely on what you said, it could be that you’re mapping the wrong variable to your service. You said you “passed bizdoc as pipeline input,” however, based on your pseudo code, your variable is actually named bizdocs. Make sure you’re mapping the right variable.
Question: how/why are you generating a list of bizdocs? I have only worked with single bizdocs in my implementations, so I am curious as to what your actual requirements are.
