Graph API returns 401 Error and error code is "UnknownError" (whole error text is written in attachment.)
- Trying to get content of callRecording and above error occurs.
https://learn.microsoft.com/en-us/graph/api/callrecording-get?view=graph-rest-1.0&tabs=python/users/{userId}/onlineMeetings/{meetingId}/recordings/{recordingId}/content - Using code is same as the sample code in documents.
from msgraph import GraphServiceClient result = await graph_client.users.by_user_id('user-id').online_meetings.by_online_meeting_id('onlineMeeting-id').recordings.by_call_recording_id('callRecording-id').get() - Using RSC of "OnlineMeetingRecording.Read.Chat" grant with the manifest.json of the teams bot, and other grants such as "ChatMember.Read.Chat" are working correctly.
- No error occurs when calling API to get metadata of callRecording
/users/{userId}/onlineMeetings/{meetingId}/recordings/{recordingId} - When using "OnlineMeetingRecording.Read.All" with same code, can get content successfully, but its grant is too strong for our service. I am supposed to use RSC grants
I assume it is either a kind of bug, or required setting is missing.
I would be grateful if you could help me. Thank you,

Can you please include how are you generating access token to call the API?

Thank you for your reply.
Below is the code to call the API.
from msgraph import GraphServiceClient from azure.identity import ClientSecretCredential credential = ClientSecretCredential( tenant_id=tenant_id, client_id=client_id, client_secret=client_secret ) graph_client = GraphServiceClient(credentials=credential, scopes=["https://graph.microsoft.com/.default"]) result = await graph_client.users.by_user_id('user-id').online_meetings.by_online_meeting_id('onlineMeeting-id').recordings.by_call_recording_id('callRecording-id').get()In my understanding, there is no need to handle access key directly when I am using msgraph on Python.
Actually, other API call works correctly except "getting content of callRecording"
I am using client_id & client_secret generated by Azure bot services.
client_id : Microsoft App ID on Azure bot service
client_secret : value of Client Secret on Azure - Certifications and Secrets
And use client_id in the manifest.json of the teams bot.
The bot is installed on the teams and as referred before, API call works correctly EXCEPT "getting content of callRecording"client_id
client_secret_id
manifest.json
The parameter "AAD_APP_CLIENT_ID" value is same as client_id
"bots": [ { "botId": "${{AAD_APP_CLIENT_ID}}", "scopes": ["team", "personal", "groupChat"], "isNotificationOnly": false, "supportsCalling": true, "supportsVideo": true, "supportsFiles": true } ],"webApplicationInfo": { "id": "${{AAD_APP_CLIENT_ID}}", "resource": "https://RscBasedStoreApp" }, -

2025-11-17T09:32:12.9433333+00:00 In addition, I found "request-id" and "client-request-id" in the error message I attached on the 1st post.
"request-id": "b5c68f0e-a45f-4d1e-9f57-49b3a336dba8" "client-request-id": "b5c68f0e-a45f-4d1e-9f57-49b3a336dba8"I am glad if it could be of any assistance.
Excerpt from an error message below:
{ "error": { "code": "UnknownError", "message":"\r\n<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\"\r\n\"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\">\r\n<html...

I put screenshots of the permissions on both Azure and Teams.
In my understanding, RSC permissions are shown on Teams, and I can see "OnlineMeetingRecording.Read.Chat" on the Admin console of Teams.
Permission on Azure
Permission on Teams

2025-11-17T09:48:32.71+00:00 Yusuke Tada, The error is because you have granted delegated API permissions and using ClientSecretCredential flow to generate access token.
To resolve the error, you need to grant OnlineMeetingRecording.Read.All, application type API permission in the Microsoft Entra ID application too.

2025-11-17T10:06:21.4833333+00:00 Thank you for suggestion, Rukmini
However, I think it is not possible to grant OnlineMeetingRecording.Read.Chat in the Microsoft Entra ID, because It is one of RFC permissions, so I can only find "OnlineMeetingRecording.All" but not "OnlineMeetingRecording.Chat".
As I preferred before, "OnlineMeetingRecording.Read.All" is too strong permission for our service. I am supposed to use RSC grants.
Please teach me if there is any way to grant OnlineMeetingRecording.Read.Chat in the Microsoft Entra ID in Azure console.

Please teach me how to do it.
Do you mean I can grant OnlineMeetingRecording.Read.Chat in the console page as the screenshot of below ?

2025-11-17T10:28:49.5566667+00:00 I see, I know I can do it using OnlineMeetingRecording.Read.All
However, it is too strong grant for our service.
As I written, am supposed to use RSC grants if I can.
In the document, it looks possible to use OnlineMeetingRecording.Read.Chat to get content of MeetingRecord.
https://learn.microsoft.com/en-us/graph/api/callrecording-get?view=graph-rest-1.0&tabs=python
Is it the document is wrong?

"OnlineMeetingRecording.Read.Chat" is not enough to resolve the problem
