Issue with calling getRecording graph api

Question

Hi guys I was trying to fetch the transcript and recording after having an online meeting that was created using the createEvent api. I was able to retrieve the transcript but not the recording ( by calling microsoft graph apis). I was able to get a successful response after calling the getRecording api but it just seems that there is not recording associated with the meeting (See pic 1) I suspect that the recording was not uploaded to the Microsoft cloud service (OneDrive for Business) as it always shows a "Recording failed to upload" message on Teams after the meeting ended (See pic 2). Any ideas on how to fix this problem/make it work? Could it be invalid config or onlineMeeting or did I miss setting up some policy with the CsTeamsMeetingPolicy? (Using delegated access for getRecording, gotten API permission for OnlineMeetingRecording.Read.All, granted CsApplicationAccessPolicy in Powershell) What else am I missing?
