THEN Ensure only AZURE_* environment variables (AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY) are set. Unset or leave undefined any OPENAI_* variables such as OPENAI_API_BASE, OPENAI_API_KEY, OPENAI_API_TYPE, or OPENAI_API_VERSION. This avoids the conflict where LangChain's AzureChatOpenAI attempts to pass both base_url (from OPENAI_API_BASE) and azure_endpoint (from AZURE_OPENAI_ENDPOINT) to the OpenAI client.

# Set only Azure-specific env vars
import os
os.environ.pop("OPENAI_API_BASE", None)
os.environ.pop("OPENAI_API_KEY", None)
os.environ["AZURE_OPENAI_ENDPOINT"] = "https://your-resource.openai.azure.com/"
os.environ["AZURE_OPENAI_API_KEY"] = "your-key"
