3004: Specified meeting is not found

HI,

I'm trying to get meeting information, and subsequently meeting attendance reports, for a January meeting, but I'm getting this error using the onlineMeetings API.

The meeting and its attendance report are correctly visible on the organizer's Teams account, but I get this error using the API.

I have made sure that all the information is correct when calling the Graph API.

Is anyone facing a similar situation or know how to fix it?

Thank you.
