Not able to invoke model external model

[Himali_K]

I have followed below steps

1) Created serving end point by for external model gpt-4-turbo and providing azure AI endpoint and key

2) Now using langchain,  i am trying to connect and invoke message from model in notebook 

model = ChatDatabricks(target_uri="databricks", endpoint="test", temperature=0.99)
response = model.invoke(messages)

But getting error as
HTTPError: 500 Server Error: Received error from openai for url: https://{test}-c2.azuredatabricks.net/serving-endpoints/testpocC/invocations.

Any other setting is required ? or any code issue

Hi @Himali_K, looks like it is a configuration or request issue. Check that the endpoint URL is correctly formatted and accessible, ensure the API key and permissions are correctly set, verify the ChatDatabricks model configuration, and make sure there are no network or firewall issues. Review logs for detailed error messages and confirm that the langchain library is properly installed and configured.
