No... that wouldn't be related since you're not doing a GROUP ALL.
The `FLATTEN(MY_UDF(t))` has me a little weary. Something is possibly going
wrong in your UDF. The output of your UDF is going to be a string that is
some generic status right? My uneducated guess is that there's a bug in
your UDF. To confirm, do you get the correct result if you replace your UDF
with an out of the box one e.g. COUNT?
