invalid_request_error on Azure Assistants API.

Question

I am getting an invalid_request_error on Azures assistants API on code that was basically basted from docs and modified only slightly to fit the codebase. The full error is: openai.NotFoundError: Error code: 404 - {'error': {'message': 'Invalid URL (POST /v1/assistants)', 'type': 'invalid_request_error', 'param': None, 'code': None}}

client = AzureOpenAI(
    api_key=os.getenv("key"),  
    api_version="2024-02-15-preview",
    azure_endpoint = os.getenv("AZURE_OPENAI_ENDPOINT")
    )

# Create an assistant

)

# Run the thread
