Create JSON schema from a class

[wegoodwin]

Hi,

Could someone provide a code example of how to take an existing class, convert it to a string so that it can be read by completechat function? I have tried using the following but I get an error:

string cm = "This is a test";

  Newtonsoft.Json.Schema.Generation.JSchemaGenerator generator = new Newtonsoft.Json.Schema.Generation.JSchemaGenerator();
  Newtonsoft.Json.Schema.JSchema schema = generator.Generate(typeof(MyClass));

ChatResponseFormat format = ChatResponseFormat.CreateJsonSchemaFormat(
                "Report_Outline",
                 BinaryData.FromString(schema.ToString()), null,
                true);

            ChatCompletionOptions options = new ChatCompletionOptions()
                {
                    ResponseFormat = format
                };

ChatCompletion chatCompletion = client.CompleteChat([new UserChatMessage(cm),], options);

Here is the error I get:
Invalid schema for response_format 'Report_Outline': schema must be a JSON Schema of 'type: "object"', got 'type: "None"'.
