SemanticKernel throws "Unrecognized request argument supplied: tools"

Question

I've just upgraded to SemanticKernel 1.0.0-rc4 and this error shows up wherever I'm using Native Functions:

Microsoft.SemanticKernel.Http.HttpOperationException
Unrecognized request argument supplied: tools
Status: 404 (model_error)

Content:
{
  "error": {
    "message": "Unrecognized request argument supplied: tools",
    "type": "invalid_request_error",
    "param": null,
    "code": null
  }
}

Here is my sample code trying to use LightPlugin in the sample docs:

OpenAIPromptExecutionSettings settings = new()
{
    ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions
};

// This line throws the exception
var result = await chatService.GetChatMessageContentsAsync(chatHistory, settings, kernel);

It works fine with semantic functions, the problem is just when I'm using native functions. The native functions were also working fine in 1.0.0-rc3.

Answer 1

The problem was that since SemanticKernel 1.0.0-rc4, it requires a gpt-turbo-35 model newer than 0614. Mine was 0301.

Good to mention that in some Azure regions (like West Europe at the time) the newer versions are not available yet. I had to create another resource on UK South so I could create a 1106 version model.
