I was very much excited to learn about semantic-kernel. I quickly jumped in to some tutorials and started trying it only to end up wasting 3 hours of my time debugging this issue. I hope this gets merged soon. Its not a good welcome for one who wants to learn semantic-kernel with Azure OpenAI account.

Workaround that I'm using now:

chat = AzureChatCompletion(service_id=service_id, api_version=azure.api_version,
                           deployment_name="gpt-4", base_url=azure.api_base+"/openai", ad_token_provider=azure.token_provider)

Note how I'm appending "/openai" to base_url

@prathyk you should be able to just change base_url to endpoint!

Hi folks. It's still an issue today. I had to append the "/openai" to the base_url to make it work. I am on sk 1.18.2.

[eavanvalkenburg]

hi, in this case you should use endpoint, and not base_url, base_url should contain the whole thing openai/deployments/{deployment_name} while endpoint will append that, see

semantic-kernel/python/semantic_kernel/connectors/ai/open_ai/services/azure_config_base.py

Line 82 in d06d230

base_url = HttpsUrl(f"{str(endpoint).rstrip('/')}/openai/deployments/{deployment_name}")

Thanks for the quick answer. I tried with endpoint but I get a "resource not found" error.

[eavanvalkenburg]

can you share the broader code? and have you validated all the params?

Thanks for the quick answer. I tried with endpoint but I get a "resource not found" error.

Please make sure your AZURE_OPENAI_API_VERSION is correct. If not, it will throw a 404. I just tested it right now and I see, via logging:

DEBUG:openai._base_client:HTTP Request: POST https://***.openai.azure.com/openai/deployments/gpt-4o-mini/chat/completions?api-version=2024-09-01-preview "200 OK"
