Review comment:
I don't think we need this list, just throw the exception on the first
null IS.

Review comment:
The original batch call is more efficient. Why do we want to change it?
You can still iterate the returned IS list but filter by the resourceNames
list. Then check if any item in the resourceNames but not in the returned IS
list.
