Thanks for getting back to me so quickly Morten! I've answered inline below.

   1. When submitting an identical post containing

Yes, what kind of error are you getting? a reference error, or a validation

1. Adding new parameters to control the output is a great idea, is this
something that you plan to implement as part of the blueprint you mention
below?
2. I'm also wondering if it would make more sense to mark the ignored
objects as "ignored" in the stats, instead of having zeros for all the
stats? I've re-attached our output, and you can see that I posted
4 programTrackedEntityAttributes, and the stats show 0 total / 0 ignored
which is not entirely accurate. I would have expected 4 total / 4 ignored.
Thoughts?

Thanks.
