OpenAIClient invalid CompletionsOptions getting generated

[cato-dll]

I'm trying to leverage the OpenAI Java samples here:

https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/openai/azure-ai-openai/src/samples/java/com/azure/ai/openai/usage/GetCompletionsSample.java

when running it, I get the error:

Status code 400, "{"error":{"code":"BadRequest","message":"logprobs, best_of and echo parameters are not available on gpt-35-turbo model. Please remove the parameter and try again. For more details, see https://go.microsoft.com/fwlink/?linkid=2227346."}}"

I setup a debugging HttpPipelinePolicy that shows that the submitted payload is:

 {"prompt":["convert the following list into a json array:  - one - two - three"],"max_tokens":800,"temperature":0.0,"top_p":1.0,"logit_bias":null,"user":null,"n":null,"logprobs":null,"echo":null,"stop":null,"presence_penalty":0.0,"frequency_penalty":0.0,"best_of":null,"stream":null,"model":null}

So the indicated "bad" values are being sent as null.

When I try the same payload via Postman, I get the same error. Remove the fields, even though null, I get the expected response.

While trying to work through the problem I checked out the source from Github, and simply added:

@Fluent
@JsonInclude(Include.NON_NULL)
public final class CompletionsOptions {

The - @JsonInclude(Include.NON_NULL), to the existing code and then everything worked as expected. All the null properties where not sent as part of the payload and the results where returned as expected.

What I don't know is should this be submitted as a defect and corrected in the base code, or is there a way to modify the Jackson configuration so that the Null values are never included -- but this will need to be done at the OpenAIClient level as I use Jackson in other parts of my code and I don't want to have a derogatory affect.

Thoughts?

Thanks in advance.
