Hi all, Is there a way to filter empty or null values in an event API query?
I am facing to a problem to get event data via API. The problem I am facing is that I can't filter on empty or null values when I am trying to access to events which have empty or null values using an API query. I've tried a query like this one: ( https://play.dhis2.org/2.29/api/events.json?program=uy2gU8kT1jF&filter=XorIxxprsOp:EQ:0) but didn't work. Could someone help me on this? Best regards, Fleury!
