Hello. I am trying to develop on Azure AI with OpenAI. I have the endpoints and generic setup working. When I try to use AzureAI with llama_index.core it still tries to do directly to an OpenAI service, not the service we have in Azure. I am following along with "Workflows for Advanced Text-2-SQL" and have changed this to llm=AzureOpenAI(...) yet it still wants to go to OpenAI. What am I missing?
