GetConversationMembersAsync, CreateConversationAsync and SendToConversationAsync now returns Unauthorized

[RicBruIAI]

Since the "MultiTenant" support has been deprecated, I must deploy bots as "SingleTenant".
I had a logic which I must return the conversation members (GetConversationMembersAsync) and for a selected member I must send a private message (CreateConversationAsync and SendToConversationAsync).

But, starting from the GetConversationMembersAsync, it triggers this excepiton:
"Operation returned an invalid status code 'Unauthorized'"

I have the following setup:

• The bot has a linked app registration (should I add new permissions there?) and such app registration is multi-tenant (I CANNOT MODIFY THIS)
• The bot is prepared like this:

var credentials = new MicrosoftAppCredentials(botConfiguration.BotAppId.ToString(), botConfiguration.BotAppSecret);
var client = new ConnectorClient(botConfiguration.BotServiceUrl, credentials);
var channelAccount = new ChannelAccount(botConfiguration.BotId, botConfiguration.BotName);
var users = await client.Conversations.GetConversationMembersAsync(channelId);

How can I fix this? This is very hurgent.

Hello @RicBruIAI , the Entra/AAD app is only for Auth between Bot and Teams Bots backend. Single Tenant for Azure bot creation and Multi-Tenant (Accounts in any organizational directory (Any Azure AD tenant – Multitenant) for AAD app is valid choice and expected to work.
Could you please share in which flow the Unauthorized Error is coming from? Is it during Auth or while calling a Bot API?

Hi, the error is coming right when calling this:
var users = await client.Conversations.GetConversationMembersAsync(channelId);

Could it be that I am missing to specify the tenant id somewhere during authentication of the client?
