.NET: [Bug]: Telemetry incorrectly shows agent responses as user messages

[hansmbakker]

Description

I created an Aspire AppHost with DevUI, and added an Agent Service project to it.

The Agent Service is an ASP.NET Core project with OpenAI-compatible endpoints and it contains a multi-agent Handoff orchestration which is itself exposed as an agent.

I see the OpenTelemetry traces in the Aspire dashboard, but all written answer messages from the agents are marked as User messages. I expected them to have the Assistant role.

It seems only some tool calls have the Assistant role

Code Sample

AppHost.cs:

var builder = DistributedApplication.CreateBuilder(args);

var apiKey = builder.AddParameter("github-models-key",
    value: "github_pat_mysecret",
    secret: true);

var openai = builder.AddOpenAI("openai")
                    .WithApiKey(apiKey)
                    .WithEndpoint("https://models.github.ai/inference");

var agentService = builder.AddProject<Projects.Handoff_AgentService>("agentservice")
        .WithReference(openai)
        .WithHttpHealthCheck("/health");

var devui = builder.AddDevUI("devui")
    .WithAgentService(agentService)
    .WaitFor(agentService);

builder.Build().Run();

Agent Service Program.cs:

var builder = WebApplication.CreateBuilder(args);

// Add service defaults & Aspire client integrations.
builder.AddServiceDefaults();

// Add services to the container.
builder.Services.AddProblemDetails();

// Learn more about configuring OpenAPI at https://aka.ms/aspnet/openapi
builder.Services.AddOpenApi();

builder.AddOpenAIClient(connectionName: "openai")
        .AddChatClient("openai/gpt-5-mini");

// In the agent service's Program.cs
//builder.AddAIAgent("agentservice", "You write short stories.");
builder.RegisterTravelBooking("agentservice");
builder.Services.AddOpenAIResponses();
builder.Services.AddOpenAIConversations();

var app = builder.Build();

app.MapOpenAIResponses();
app.MapOpenAIConversations();

// Configure the HTTP request pipeline.
app.UseExceptionHandler();

if (app.Environment.IsDevelopment())
{
    app.MapOpenApi();
}

app.MapDefaultEndpoints();

app.Run();

Before I hand things off to the hotel and transportation specialists, a few quick questions so I can find the best options for you:\\n\\n1. Travel and hotel basics\\n- Where are you coming from (city or airport)? Do you need hotel nights before and/or after the concert? (Common choice: check in Nov 20, check out Nov 21.)\\n- How many guests/rooms and bed preference?\\n- Budget per night (economy / mid-range / premium / luxury)?\\n- Any must-have hotel amenities (parking, free breakfast, gym, early check-in, pet-friendly, accessible room)?\\n- Do you prefer a refundable rate or a cheaper non-refundable special?\\n\\n2. Location and walking preference\\n- How close to Climate Pledge Arena would you like the hotel? (within walking distance ~0–0.5 miles, short ride ~0.5–1.5 miles, no preference)\\n\\n3. Transportation details\\n- Do you want transportation only from the hotel to the arena for the concert, round-trip the same night, also airport-to-hotel, or all of the above?\\n- Preferred transport type: rideshare/taxi, private car, limo, shuttle, public transit (monorail/light rail), or flexible?\\n- Any accessibility needs (wheelchair-accessible vehicle)?\\n- Do you want a scheduled pickup at a set time or an on-demand ride?

Options: within walking distance (~0–0.5 miles), short ride (~0.5–1.5 miles), no preference.\\n\\n5) Transportation scope & preferences\\n- Which transfers do you want booked? (airport → hotel only; hotel → arena only; round‑trip hotel↔arena same night; airport→hotel + hotel↔arena roundtrip; or all including return to airport)\\n- Vehicle type preference: rideshare/taxi, private car, shuttle, public transit, or flexible?\\n- Accessibility needs? (wheelchair‑accessible vehicle needed?)\\n- Pickup timing: for the concert I recommend leaving the hotel ~60–90 minutes before the 7:30 PM start — I suggest a 6:00 PM pickup. For your airport arrival (2:00 PM), would you like a scheduled pickup at 2:30 PM (gives time for deplaning and luggage) or do you prefer on‑demand when you land?\\n\\n6) Other\\n- Any hotel loyalty program or preferred chain?\\n- Will you need parking at the hotel?\\n- Any other requests (early check‑in, crib, smoking/non-smoking, pets)?\\n\\nIf you’d like me to proceed now with defaults, I’ll hand off to the hotel and transportation agents. My recommended defaults (tell me “go ahead” to use these):\\n- Airport: SEA\\n- Room: 1 room for 2 guests, 1 king bed\\n- Rate: refundable\\n- Amenities: free Wi‑Fi + gym + breakfast if available\\n- Location: within walking distance (0–0.5 mi)\\n- Transfers: airport→hotel (scheduled at 2:30 PM) and hotel→arena roundtrip same night (pickup at 6:00 PM, return after show to hotel)\\n- Vehicle: private car (can change to rideshare)\\n\\nWhich of the above would you like to confirm or change?\"\r\n      }\r\n    ]\r\n  },\r\n  {\r\n    \"role\": \"user\",\r\n    \"parts\": [\r\n      {\r\n        \"type\": \"text\",\r\n        \"content\": \"Go ahead\"\r\n      }\r\n    ]\r\n  }\r\n]"

Before I hand things off to the hotel and transportation specialists, a few quick questions so I can find the best options for you:\\n\\n1. Travel and hotel basics\\n- Where are you coming from (city or airport)? Do you need hotel nights before and/or after the concert? (Common choice: check in Nov 20, check out Nov 21.)\\n- How many guests/rooms and bed preference?\\n- Budget per night (economy / mid-range / premium / luxury)?\\n- Any must-have hotel amenities (parking, free breakfast, gym, early check-in, pet-friendly, accessible room)?\\n- Do you prefer a refundable rate or a cheaper non-refundable special?\\n\\n2. Location and walking preference\\n- How close to Climate Pledge Arena would you like the hotel? (within walking distance ~0–0.5 miles, short ride ~0.5–1.5 miles, no preference)\\n\\n3. Transportation details\\n- Do you want transportation only from the hotel to the arena for the concert, round-trip the same night, also airport-to-hotel, or all of the above?\\n- Preferred transport type: rideshare/taxi, private car, limo, shuttle, public transit (monorail/light rail), or flexible?\\n- Any accessibility needs (wheelchair-accessible vehicle)?\\n- Do you want a scheduled pickup at a set time or an on-demand ride? (I recommend leaving the hotel about 60–90 minutes before the 7:30 PM start — so around 5:45–6:30 PM — to allow for traffic and entry lines. Tell me your preference.)\\n\\n4. Anything else\\n- Any loyalty programs or specific hotel chains you prefer?\\n- Will you need parking at the hotel?\\n\\nIf you’d like, I can suggest a few nearby hotels across different budgets right now and recommend a pickup time. Once you confirm the answers above (or tell me to proceed with defaults), I’ll contact the HotelReservationAgent to find and hold rooms and the TransportationAgent to reserve your ride. Which details would you like to confirm first?\"\r\n      }\r\n    ]\r\n  },\r\n  {\r\n    \"role\": \"user\",\r\n    \"parts\": [\r\n      {\r\n        \"type\": \"text\",\r\n        \"content\": \"Coming from the airport, arriving 2pm.

(I assume Seattle–Tacoma Intl / SEA unless you tell me otherwise.)\\n\\n2) Room & bed\\n- One room for 2 people OK? Bed preference: 1 king/queen or 2 beds?\\n\\n3) Rate type & amenities\\n- Refundable flexibility: prefer refundable or cheaper non‑refundable?\\n- Must-have amenities? (examples: free breakfast, on-site parking, gym/fitness center, early check‑in, pet‑friendly, accessible room)\\n\\n4) Location / walking preference\\n- How close to Climate Pledge Arena would you like the hotel? Options: within walking distance (~0–0.5 miles), short ride (~0.5–1.5 miles), no preference.\\n\\n5) Transportation scope & preferences\\n- Which transfers do you want booked? (airport → hotel only; hotel → arena only; round‑trip hotel↔arena same night; airport→hotel + hotel↔arena roundtrip; or all including return to airport)\\n- Vehicle type preference: rideshare/taxi, private car, shuttle, public transit, or flexible?\\n- Accessibility needs? (wheelchair‑accessible vehicle needed?)\\n- Pickup timing: for the concert I recommend leaving the hotel ~60–90 minutes before the 7:30 PM start — I suggest a 6:00 PM pickup. For your airport arrival (2:00 PM), would you like a scheduled pickup at 2:30 PM (gives time for deplaning and luggage) or do you prefer on‑demand when you land?\\n\\n6) Other\\n- Any hotel loyalty program or preferred chain?\\n- Will you need parking at the hotel?\\n- Any other requests (early check‑in, crib, smoking/non-smoking, pets)?\\n\\nIf you’d like me to proceed now with defaults, I’ll hand off to the hotel and transportation agents. My recommended defaults (tell me “go ahead” to use these):\\n- Airport: SEA\\n- Room: 1 room for 2 guests, 1 king bed\\n- Rate: refundable\\n- Amenities: free Wi‑Fi + gym + breakfast if available\\n- Location: within walking distance (0–0.5 mi)\\n- Transfers: airport→hotel (scheduled at 2:30 PM) and hotel→arena roundtrip same night (pickup at 6:00 PM, return after show to hotel)\\n- Vehicle: private car (can change to rideshare)\\n\\nWhich of the above would you like to confirm or change?\"\r\n      }\r\n    ]\r\n  },\r\n  {\r\n    \"role\": \"user\",\r\n    \"parts\": [\r\n      {\r\n        \"type\": \"text\",\r\n        \"content\": \"Go ahead\"\r\n      }\r\n    ]\r\n  },\r\n  {\r\n    \"role\": \"assistant\",\r\n    \"name\": \"HotelReservationAgent\",\r\n    \"parts\": [\r\n      {\r\n        \"type\": \"tool_call\",\r\n        \"id\": \"call_i7rlVbqa1SgTAokKzcqLFhji\",\r\n        \"name\": \"SelectRoomPreference\",\r\n        \"arguments\": {\r\n          \"city\": \"Seattle\",\r\n          \"dateOfBooking\": \"2026-11-20T14:00:00\"\r\n        }\r\n      }\r\n    ]\r\n  },\r\n  {\r\n    \"role\": \"tool\",\r\n    \"parts\": [\r\n      {\r\n        \"type\": \"tool_call_response\",\r\n        \"id\": \"call_i7rlVbqa1SgTAokKzcqLFhji\",\r\n        \"response\": [\r\n          {\r\n            \"roomId\": 309,\r\n            \"roomType\": \"Suite\",\r\n            \"pricePerNight\": 320.00,\r\n            \"hotelName\": \"Budget Stay\",\r\n            \"numberOfAdultsAllowedInRoom\": 4,\r\n            \"amenities\": \"Free WiFi, TV, Air Conditioning, Kitchenette\",\r\n            \"city\": \"Seattle\"\r\n          },\r\n          {\r\n            \"roomId\": 318,\r\n            \"roomType\": \"Suite\",\r\n            \"pricePerNight\": 410.00,\r\n            \"hotelName\": \"Mountain Lodge\",\r\n            \"numberOfAdultsAllowedInRoom\": 4,\r\n            \"amenities\": \"Free WiFi, TV, Mini Bar, Kitchenette, Fireplace\",\r\n            \"city\": \"Seattle\"\r\n          },\r\n          {\r\n            \"roomId\": 339,\r\n            \"roomType\": \"Suite\",\r\n            \"pricePerNight\": 355.00,\r\n            \"hotelName\": \"Opera Hotel\",\r\n            \"numberOfAdultsAllowedInRoom\": 4,\r\n            \"amenities\": \"Free WiFi, TV, Mini Bar, Kitchenette\",\r\n            \"city\": \"Seattle\"\r\n          }\r\n        ]\r\n      }\r\n    ]\r\n  }\r\n]"

🤖 Automated triage reproduction notes (agent-authored — trust but verify)

Agent analysis

Repro: HandoffAgentExecutor.ContinueTurnAsync() in dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs line 242 calls ChangeAssistantToUserForOtherParticipants which mutates ChatMessage.Role in-place to User before InvokeAgentAsync (line 245), where M.E.AI telemetry captures gen_ai.input.messages with wrong roles; roles are only reset at line 253 after telemetry has already logged them. Minimal repro: create a two-agent handoff workflow, have first agent respond with text+handoff, observe second agent receives prior agent messages with ChatRole.User instead of ChatRole.Assistant.
