.Net: Getting empty response when i call the planner

[Cobra86]

Describe the bug I'm sorry if it's not a bug but I tried everything and i can't find a fix. I'm getting this issue where calling the planner in the latest version results in an empty response. Also, I tested this with the planner sample project, specifically the MathSolver. https://github.com/MicrosoftDocs/semantic-kernel-docs/tree/main/samples/dotnet/11-Planner

To Reproduce Steps to reproduce the behavior:

1. Run the project.
2. Ask AI to add two numbers 2 and 1.
3. Return empty response.

I'm getting empty response for any question that trigger the planner.

Expected behavior It should return a response.

@Cobra86, are you able to share what the generated Handlebars planner looks like when there is an "empty response"? This might be a regression on the Handlebars planner.

It's not hitting the Handlebars method. This is program.cs for the test project. I'm using the MathSolver from semantic kernel samples

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.SemanticKernel;
using Microsoft.SemanticKernel.ChatCompletion;
using Microsoft.SemanticKernel.Connectors.OpenAI;
using TestOpenAIConsoleApp;

using ILoggerFactory loggerFactory = LoggerFactory.Create(builder =>
{
    builder
        .SetMinimumLevel(0)
        .AddDebug();
});

// Create kernel
var builder = Kernel.CreateBuilder();

builder.AddAzureOpenAIChatCompletion(  
         endpoint: ", // Azure OpenAI Endpoint
         apiKey: "");      // Azure OpenAI Key;
builder.Services.AddLogging(c => c.AddDebug().SetMinimumLevel(LogLevel.Trace));
builder.Plugins.AddFromType<MathSolver>();

//builder.Plugins.AddFromType<MathSolver>();
var kernel = builder.Build();

ChatHistory Messages = [];

// Get chat completion service
var chatCompletionService = kernel.GetRequiredService<IChatCompletionService>();

// Start the conversation
while (true)
{
    // Get user input
    Console.Write("User > ");
    Messages.AddUserMessage(Console.ReadLine()!);

    // Enable auto function calling
    OpenAIPromptExecutionSettings openAIPromptExecutionSettings = new()
    {
        ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions
    };

    // Get the response from the AI
    var result = chatCompletionService.GetStreamingChatMessageContentsAsync(
        Messages,
        executionSettings: openAIPromptExecutionSettings,
        kernel: kernel);

    // Stream the results
    string fullMessage = "";
    var first = true;
    await foreach (var content in result)
    {
        if (content.Role.HasValue && first)
        {
            Console.Write("Assistant > ");
            first = false;
        }
        Console.Write(content.Content);
        fullMessage += content.Content;
    }
    Console.WriteLine();

    // Add the message from the agent to the chat history
    Messages.AddAssistantMessage(fullMessage);
}

It appears there was an issue with Azure OpenAI UK, but I can now see the response. I'll keep this issue open, as it seems the code isn't handling it properly.

[madsbolaris]

We got word that it's been fixed. Are you still getting the issue?

[Cobra86]

Yes, It's fixed. In future, will the code handle this issue? I'm not sure what was the issue and is it good practice to throw error when the response is empty ?
