The api value returned for the owner is returning empty

Question

Hi Support Team,

1
In my SharePoint app , i use this api to get all resource event
http://users/{resource.mail}/calendarView?$top=1000&startDateTime=${start}&endDateTime=${end}&$select=iCalUId,start,subject,end,seriesMasterId,isCancelled

and value return meeting room information ( iCalUid and id ... )

2
And when I use: https://graph.microsoft.com/v1.0/users/${mail}/calendarView?$top=1&startDateTime=${start}&endDateTime=${end}&$filter=iCalUId eq '${iCalId}'
with iCalId above

it returns: value: [] . ${mail} is the owner who created the event.

3
But when I use: https://graph.microsoft.com/v1.0/users/${resource.mail}/events/${id} it returns all the information.

My expectation is that when the owner calls the calendarView API, it should return the full event information.

4 Api access sharepoint

MailboxSettings.Read
Group.Read.All
User.Read.All
Calendars.ReadWrite.Shared

Thanks!
