JsonSerializationException on CreateChatCompletion

[mifu67]

Describe the bug Calling CreateChatCompletion results in a JsonSerializationException when attempting to deserialize the CreateChatCompletionResponse object. Full error: JsonSerializationException: Could not find member 'system_fingerprint' on object of type 'CreateChatCompletionResponse'. Path 'system_fingerprint', line 21, position 23.

To Reproduce Steps to reproduce the behavior:

1. Call the following:

   var completionResponse = await openai.CreateChatCompletion(new CreateChatCompletionRequest() { Model = "gpt-4-1106-preview", Messages = [list of messages], Temperature = 0.0f, }

Expected behavior A populated completionResponse.

Environment:

• OS: MacOS Ventura version 13.4
• Unity Version [e.g. 2022.3.7f1]
• Plugin Version [e.g. 0.1.5]

Context: This was working yesterday. Maybe the OpenAI API updated?

Hi @mifu67 my guess also is that Open AI might have made system_fingerprint mandatory in the response type. Can you add public SystemFingerprint object { get; set; } in CreateChatCompletionResponse here to see if that fixes the issue?

I do not have an API Key, so I wont be able to test it unfortunately.

@srcnalt yes, that fixes the issue. Thanks!
