Describe the bug
When running the test Step04_AgentOrchestration, this is shown but tests passes:

Step04.Step04_AgentOrchestration.DelegatedGroupChatAsync

  Source: Step04_AgentOrchestration.cs line 33

To Reproduce
Steps to reproduce the behavior:

1. Configure secrets with gpt-4o-mini
2. Run the test
3. See error

Expected behavior
A conversation between a Manager and a User takes place. The final sentences looks like:

    [00:34] USER: That's all, thank you
    [00:34] ASSISTANT - Manager: You're welcome! If you need anything else in the future, just let me know. Have a great day!

Platform

• Language: C#
• Source: (https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/GettingStartedWithProcesses/Step04/Step04_AgentOrchestration.cs)
• AI model: Azure OpenAI GPT-4o-mini latest.
• IDE: Visual Studio
• OS: Windows

Additional context
Managed to fix the issue, but need you to double check.

The root problem is at: https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/GettingStartedWithProcesses/Step04/Steps/ManagerAgentStep.cs line 107. It is trying to retrieve the 'ResponseFormat' for IntentResult from:

private static readonly ChatResponseFormat s_intentResponseFormat = ChatResponseFormat.CreateJsonSchemaFormat(
        jsonSchemaFormatName: "intent_result",
        jsonSchema: BinaryData.FromString(JsonSchemaGenerator.FromType<IntentResult>()),
        jsonSchemaIsStrict: true);

Looks like it is not working just return the type of IntentResult:

private static readonly Type s_intentResponseFormat = typeof(IntentResult);

As stated in Structured Outputs with System.Type.

Suggestion
Make the test fail if something weird happen:

In https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/GettingStartedWithProcesses/Step04/Steps/RenderMessageStep.cs, add an Assert.Fail() on RenderError Function:

    /// <summary>
    /// Render exception
    /// </summary>
    [KernelFunction]
    public void RenderError(KernelProcessError error, ILogger logger)
    {
        string message = string.IsNullOrWhiteSpace(error.Message) ? "Unexpected failure" : error.Message;
        Render($"ERROR: {message} [{error.GetType().Name}]{Environment.NewLine}{error.StackTrace}");
        logger.LogError("Unexpected failure: {ErrorMessage} [{ErrorType}]", error.Message, error.Type);
        Assert.Fail();
    }

Thanks,
