grouping.json (97.7 KB) shows two Change Nodes using Jsonata being used to de-duplicate log entries.
The first node groups & amends objects from a log by (day) date, the second strips off the date key produced by that grouping such that a simple array of objects is produced; exactly like the input.
It works fine. (There a 8 or 9 fewer elements in the clean output array than the input.)
However, I feel it's a bit feeble having to use two nodes but I couldn't find a syntax / method of grouping without having to use that grouping (day/date in this case) as an output key somewhere.
I'd be very grateful for any thoughts.
