@Yuto-24 Thank you for reporting this issue to our team! I'm leaving some notes here for other contributors to help with this issue.

Here is the definition of the Azure provider:

class AzureChatOpenAIProvider(BaseProvider, AzureChatOpenAI):
    id = "azure-chat-openai"
    name = "Azure OpenAI"
    models = ["*"]
    model_id_key = "azure_deployment"
    model_id_label = "Deployment name"
    pypi_package_deps = ["langchain_openai"]
    # Confusingly, langchain uses both OPENAI_API_KEY and AZURE_OPENAI_API_KEY for azure
    # https://github.com/langchain-ai/langchain/blob/f2579096993ae460516a0aae1d3e09f3eb5c1772/libs/partners/openai/langchain_openai/llms/azure.py#L85
    auth_strategy = EnvAuthStrategy(
        name="AZURE_OPENAI_API_KEY", keyword_param="openai_api_key"
    )
    registry = True

    fields = [
        TextField(key="azure_endpoint", label="Base API URL (required)", format="text"),
        TextField(key="api_version", label="API version (required)", format="text"),
    ]

The Azure endpoint is being passed via the azure_endpoint keyword parameter. However, this may have been renamed, which may be causing the issue you are describing.

We should find the definition of AzureChatOpenAI, see which keyword parameter it expects for AZURE_OPENAI_ENDPOINT, and then update the key defined in the field.

Exactly. I also found this, but I couldn't detect where it is used.

I hope someone who knows this arch will resolve this issues.
