Missing shifts data after applying the filter in Microsoft Graph APIs

Question

Hi we have more than 170 teams in our organization and pulling Graph API shifts data for them. Recently we have found out
that we are not getting shifts data for the date of 2020-12-15 and 2020-12-16 for a particular team member in a particular
team. We do not know we will have same issue for other teams as well.

Filer details: sharedShift/startDateTime ge 2020-12-14T00:00:00.000Z and sharedShift/endDateTime le 2021-02-18T00:00:00.000Z

However ,when we do not apply the filter we are able to get all the expected data. Could you please email me the solutions.

Answer 1

var shifts = await graphSC.graphServiceClient.Teams["OurParticularTeamId"].Schedule.Shifts

             .Request().Filter("sharedShift/startDateTime ge 2020-12-14T00:00:00.000Z and sharedShift/endDateTime le 2021-02-18T00:00:00.000Z")  
           .GetAsync();  

I am using the above C# code. But for your reference, this is the API details "GET /teams/{teamId}/schedule/shifts".You can find out more from the below link
