Microsoft Graph API: UnknownError when i am trying to get a call

Question

I am trying to get the subject (ex. Maths 1) of an online TEAMS meeting via Microsoft Graph API.

When i send a request to https://graph.microsoft.com/v1.0/communications/callRecords/8f4477a7-f5b2-40ed-a165-95519825c9cg in the response there is no value for the subject of the meeting.

So my next move is to send a request to https://graph.microsoft.com/v1.0/communications/calls/8f4477a7-f5b2-40ed-a165-95519825c9cg because the Graph API documentation has the property 'subject' in the response. When i send this request i get this response:

{
"error": {
    "code": "UnknownError",
    "message": "",
    "innerError": {
        "date": "2021-02-10T12:32:19",
        "request-id": "9a81a114-8a58-457b-929v-390bda79669g",
        "client-request-id": "9a81a114-8a58-457b-929a-490bda79669g"
    }
}

}

with a response status code : 500 Interval Server Error from the Graph API.

I have tried this request with different meeting ids but the result is the same.

My API permissions are these: API Permissions

I would appreciate it if I had a solution to my problem or some other way to find the subject of the meeting.

Maybe you're not using an authorization with you token in the request header. You can follow this documentation to get further help. — smlj

The reason why you are getting that error is because you are querying the teams meeting as a resource of type 'call' instead of 'event'.

Please use GET https://graph.microsoft.com/v1.0/users/{id |userPrincipalName}/events/{id} using Calendars.Read Application permission when querying as an application or GET https://graph.microsoft.com/v1.0/me/calendar/events/{id} with the Calendars.Read delegated permissions when querying as a signed-in user. For further reference, have a look at https://docs.microsoft.com/en-us/graph/api/event-get?view=graph-rest-1.0&tabs=http
