Proxy is not respected

I followed the steps here and its not using the proxy at all. My requests just time out: https://learn.microsoft.com/en-us/graph/sdks/customize-client?tabs=python#configuring-the-http-proxy-for-the-client

While normal requests using httx work, the requests to Azure do not. I'm guessing that this new client is not accepted somewhere down the chain

import asyncio
from azure.identity.aio import ClientSecretCredential
from django.conf import settings
from httpx import AsyncClient
from kiota_authentication_azure.azure_identity_authentication_provider import (
    AzureIdentityAuthenticationProvider,
)
from msgraph import GraphRequestAdapter, GraphServiceClient
from msgraph.generated.users.users_request_builder import UsersRequestBuilder
from msgraph_core import GraphClientFactory


def get_azure_client() -> tuple[GraphServiceClient, AsyncClient]:
    credential = ClientSecretCredential(
        settings.AZURE_TENANT_ID, settings.AZURE_CLIENT_ID, settings.AZURE_CLIENT_SECRET  # type: ignore
    )
    auth_provider = AzureIdentityAuthenticationProvider(
        credential, scopes=["https://graph.microsoft.com/.default"]
    )
    # see: https://learn.microsoft.com/en-us/graph/sdks/customize-client?tabs=python#configuring-the-http-proxy-for-the-client
    httpx_proxies = {
        "http://": settings.INTERNET_PROXY,
        "https://": settings.INTERNET_PROXY,
    }
    http_client = AsyncClient(proxies=httpx_proxies)  # type: ignore
    http_client = GraphClientFactory.create_with_default_middleware(client=http_client)
    adapter = GraphRequestAdapter(auth_provider, http_client)
    return GraphServiceClient(request_adapter=adapter), http_client


async def amain() -> None:
    client, http_client = get_azure_client()
    await http_client.get("https://microsoft.com") # this works
    await client.groups.by_group_id(  # this times out
        settings.AZURE_GROUP_ID
    ).transitive_members.get()


if __name__ == "__main__":
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    try:
        loop.run_until_complete(amain())
    except KeyboardInterrupt:
        pass

GraphClientFactory.create_with_default_middleware と GraphRequestAdapter から始め、次に AsyncClient の直接リクエストと GraphServiceClient のリクエストを比較します。提供されたプロキシ設定を使ってタイムアウトを再現し、設定済みの AsyncClient がミドルウェアとアダプターを通じて維持されているかを追跡します。Graph リクエストがタイムアウトするのではなく、設定済みのプロキシを使用すれば完了です。
