I'm encountering a situation in which a QuerySet qs I construct has a positive number of records, as confirmed by qs.count() being over 1 million. However, when I try to iterate through those records using qs.iterator(), there're no iterations being performed.

I try reconstructing the queryset and test: test_iterator = qs.interator(); next(test_iterator) -- and I confirm that this returns the StopIteration error, which means the iterator is indeed empty."
