I'm trying to filter an array based on some values nested in objects.
My data pertains to offers (array), customers(array) with tickets(array) and other child arrays. I want to orderBy to get all the customers information ordered by the latest timeStamp (attribute in tickets array)
From the example, offer 1 has customer 50001 with tickets 1001, 1002 and customer 50002 with tickets 1003, 1004. I want the customer which has latest timestamp in all the tickets available to be displayed first: (Desc order) with all the other passengers ordered accordingly.
Request Payload:
