Who is onCall API returns empty array

[Stefanie Metzger]

I am calling this api: 

https://api.eu.opsgenie.com/v2/schedules/b8...b9/on-calls?scheduleIdentifierType=id&date=2025-11-18T09:00:00%2B02:00

This worked as expected in the last weeks, but stopped working in the last days.

The response is just an empty array for onCallParticipants, although someone is assigned to this. It happens for all schedules i tried and it happens also for both scheduleIdentifierType name and id. It also happens when overwrites are set or not.

This is breaking our automation built on top of this feature. A quick fix or workaround for this would be highly apprechiated.

{

   "data": {

   "_parent": {

      "id": "b8...b9",

       "name": "ConnectorsBusinessHoursSchedule",

       "enabled": true

       },

    "onCallParticipants": []

    },

   "took": 0.018,

   "requestId": "1fd...b6"

}

Solution: This was caused by the time shift as after the time shift the time i requested data for no-one was assigned to the role.
