Bad request when I call graph api for online meeting registration data

Question

I created a Webinar using Teams desktop app. It requires users to register using registration form.

Following this url: https://learn.microsoft.com/en-us/graph/api/meetingregistration-get?view=graph-rest-beta&tabs=http

I successfully retrieve OnlineMeeting Data using:

https://graph.microsoft.com/beta/me/onlineMeetings/{id}

Instead, when I tried to get registration data from graph api BETA, I goy a Bad Request as response for the query:

https://graph.microsoft.com/beta/me/onlineMeetings/{id}/registration

Even using https://developer.microsoft.com/en-us/graph/graph-explorer, when I try the query, I got this response:

{
    "error": {
        "code": "BadRequest",
        "message": "Bad Request",
        "innerError": {
            "date": "2023-11-20T11:33:59",
            "request-id": "aee4eb64-6a84-49e2-b33b-43240a33ce0a",
            "client-request-id": "499a8990-7091-2da3-d558-a5b1e473fc1d"
        }
    }
}
