Why do we get a `openai.error.InvalidRequestError` if we pass `None` to `logit_bias` even if it defaults to `null`?

[nbro10]

Describe the bug

According to the docs, logit_bias defaults to null, but if we pass None to this parameter we get openai.error.InvalidRequestError

openai.error.InvalidRequestError: None is not of type 'object' - 'logit_bias'

So, I suppose this is a bug in this package, as None should correspond to what the docs refer to as null, or the documentation is wrong.

To Reproduce

Use the script below

Code snippets

import openai

completions = openai.Completion.create(model="text-davinci-003",
                                       prompt="hello",
                                       logit_bias=None)
print(completions)

I have experienced the same problem. In the documentation it is stated, that the default value should be null. However, when providing it explicitly, I'm getting the same error in the Postman as OP.

As far as I have investigated the API. It looks like providing the empty map has fixed the problem. So I believe, that there are two solutions here. First one would be changing the documentation and providing the "Defaults to empty map". Second one would be changing the API so it can accept the null value as logit_bias parameter.

Looking forward for any updates on this case and decided solution from the developers.

I will have the team take a look at this later this week.

Closing because this is an API issue rather than an SDK issue.
