Bug: filtering by due date fails in Zoho Desk API tickets search endpoint

Bug: filtering by due date fails in Zoho Desk API tickets search endpoint

Steps to reproduce:

GET /api/v1/tickets/search?limit=100&dueDateRange=2019-06-30T16:40:00.000Z,2019-06-30T16:50:00.000Z&sortBy=createdTime

Result: the response returns all tickets from the beginning of time, regardless of due date.

Expected result: it should only return tickets whose due date is between 2019-06-30T16:40:00.000Z and 2019-06-30T16:50:00.000Z.

It was working perfectly fine until today (30/06/20) around 11:55 UTC, when it suddenly started ignoring the dueDateRange query parameter. Probably the result of some deploy around that time?
