Calling openai.beta.chat.completions.runTools with gpt-4-32k returns error: "Additional properties are not allowed ('parsed', 'refusal' were unexpected)"

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

I am using the example from https://github.com/openai/openai-node/blob/master/examples/tool-call-helpers.ts and using OpenAI node SDK v.4.69.0.

When I execute the example using gpt-4-32k model, I receive the following error: BadRequestError: 400 Additional properties are not allowed ('parsed', 'refusal' were unexpected) - 'messages.2'

When I execute the example using gpt-4o model, the example works correctly.

I have been testing with different OpenAI node SDK versions. The last one where runTools actually works with this example is v.4.54.0. Once you upgrade to 4.55.x the error starts happening.

It could be related with the addition of Structured outputs that was added in 4.55.x.

I am using GPT models deployed in an Azure OpenAI service.

Maybe I should be doing something different to make it work with gpt-4-32k? (I haven't tested with gpt-4-1106-preview that is used in the example, but this should also work with gpt-4-32k, right?).

To Reproduce

• Use the example available at https://github.com/openai/openai-node/blob/master/examples/tool-call-helpers.ts
• Configure the OpenAI instance to use a GPT4 32k model.
• Execute the example
