Unable to fetch Active Participants in Teams Meeting

[pavankalyan066]

Describe the issue
We have developed an application that invites Recording Bot to join the active Teams meeting. Basically It updates the context of Bot with activate participants of the meeting so that it can perform active transcription of audio stream which was working fine but Recently when we create new version of Bot image with same version of packages The Bot is not able to get the Active Participants of the meeting.

Code Snippet
this.Call = statefulCall;
this.Call.OnUpdated += this.CallOnUpdated;
this.Call.Participants.OnUpdated += this.ParticipantsOnUpdated;
this.GraphLogger.Log(System.Diagnostics.TraceLevel.Warning, $"Starting call with id: {this.Call.Id}");

Expected behavior
It should identify all the active participants so that it get identify the stream of user and process it.

Graph SDK (please complete the following information):
Microsoft.Graph.Communications.Calls -1.2.0.850
Microsoft.Graph.Communications.Calls.Media - 1.2.0.850
Microsoft.Skype.Bots.Media - 1.19.0.25-alpha

Call ID
3c003780-5f6b-4d7f-8777-ff3043c63a3b

Logs
The callid is empty in the logs

Additional context

Hi @pavankalyan066, thanks for raising your issue. Could you please let us know what you mean by Recently when we create new version of Bot image with same version of packages. Are you creating a new bot and only updating the app package with newly created bot id? Also, could you please share the sample/doc reference link which you followed?

[pavankalyan066]

Hi @Prasad-MSFT

What I mean is creating a new image of Bot with same packages is not working as before.

Please find github sample for your reference

Feel free to ask any other queries.
