What should be the value of ServiceUrl in the ConnectionsMap.ServiceUrl for multiple agent endpoints?

[pujan-tafe]

I followed the instructions in the Retrieval bot sample. This is the link for the appsettings.json: https://github.com/microsoft/Agents/blob/main/samples/dotnet/RetrievalBot/appsettings.json

The single bot works fine, but I could not find how to configure multiple agents.
I am trying to add multiple agents in the same project. So, the message endpoints are:

1. /api/agents/agent-1/messages
2. /api/agents/agent-2/messages

Everything works well locally for both messaging endpoint.

Now, during hosting in Azure Bot, I need to configure the Connections - BotServiceConnections.
I could only make it work with one agent. In all the samples I have seen so far, the value for ServiceUrl is *. So any request maps to that ServiceConnection. But, I want to selectively map the service connections based on message endpoints.

My current approach is:

  Connections: {
  "Agent1ServiceConnection": {Credentials properties}
  "Agent2ServiceConnection":{Credentials properties}
  }
  ConnectionMaps: [
    {
       "ServiceUrl": "/api/agents/agent-1/messages"
       "Connection":"Agent1ServiceConnection"
    }
    {
      "ServiceUrl": "/api/agents/agent-2/messages"
       "Connection":"Agent2ServiceConnection"
    }
  ]

This gives object null exception. An instance of IAccessTokenProvider not found.

Please suggest what should be value for ServiceUrl in above config.

@pujan The expected name for the mappings is ConnectionsMap. The ServiceUrl is from the Activity received, not the endpoint. For this, I would use the Audience instead:

  "ConnectionsMap": [
    {
      "Audience": "{{ClientId1}}",
      "Connection": "Agent1ServiceConnection"
    },
    {
      "Audience": "{{ClientId2}}",
      "Connection": "Agent2ServiceConnection"
    }
  ],

@tracyboehrer. Awesome. The 'Audience' property helped. Thank you so much.
