API Spec version

Describe the bug

Setting parallel_tool_calls = false without additional data sources is working. However pairing an azure search index with tools throws a validation error. Is also the case with 2024-10-01-preview.

Expected behavior

Access to data from the azure search index and the available functions defined in the tools parameter

Actual behavior

response = client.chat.completions.create( openai.BadRequestError: Error code: 400 - {'error': {'requestid': 'd193933e-ea16-4e56-9d62-e1974b01b92c', 'code': 400, 'message': 'Validation error at #/parallel_tool_calls: Extra inputs are not permitted'}}

Reproduction Steps

from openai import AzureOpenAI # 1.51.1
from azure.identity import DefaultAzureCredential, AzureAuthorityHosts, get_bearer_token_provider


client = AzureOpenAI(
    azure_endpoint="###", # your azure endpoint
    api_key="###", # either bearer token provider or api key
    api_version="2024-09-01-preview", 
    )

response = client.chat.completions.create(
                model="gpt-4o",  # your model
                messages=[
                    {"role": 'user', "content": 'Please use a tool'} # message is irrelevant, could also be "hello"
                ],
                stream=False,
                tools=[{
                    'type': 'function',

                        }
                }],
                tool_choice='auto',
                parallel_tool_calls=False,
