Function call didn't work. Because of Deserialization issue

[ebattulga]

I'm using Function. But deserializer choose wrong class ChatGPTChatCompletionMessage instead of ChatGPTAssistantCompletionMessage.

Function call return Assistant Completion response. But deserializer always return ChatCompletion class and missing some properties. This is actual returning json

{
  "id": "chatcmpl-8icO5Kj0IEqgDr6dU9J0E9Gecv4nQ",
  "object": "chat.completion",
  "created": 1705644685,
  "model": "gpt-3.5-turbo-0613",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": null,
        "tool_calls": [
          {
            "id": "call_Ww3ocoHqydw5xhnS5H1CZImu",
            "type": "function",
            "function": {
              "name": "getExchangeRate",
              "arguments": "{\n  \"currency\": \"USD\"\n}"
            }
          }
        ]
      },
      "logprobs": null,
      "finish_reason": "tool_calls"
    }
  ],
  "usage": {
    "prompt_tokens": 99,
    "completion_tokens": 16,
    "total_tokens": 115
  },
  "system_fingerprint": null
}

But after deserialized object looks like this

{
    "Id": "chatcmpl-8iKN8vlb6QEYiGukfWLAlJNG0jS2V",
    "Object": "chat.completion",
    "Created": "2024-01-18T10:57:14Z",
    "Model": "gpt-3.5-turbo-0613",
    "Choices": [
        {
            "Index": 0,
            "Message": {
                "Role": "assistant",
                "Content": null,
                "Name": null
            },
            "FinishReason": "tool_calls"
        }
    ],
    "SystemFingerprint": null,
    "Usage": {
        "PromptTokens": 97,
        "CompletionTokens": 16,
        "TotalTokens": 113
    }
}

How to fix this to deserialized by ChatGPTAssistantCompletionMessage class.

Please upgrade to version 1.8.0. This was an oversight in the definition of the response message.
