'HTTPTransport' object has no attribute '__aenter__'

Getting a traceback when running the snippet below.
Is this a bug or am I doing something wrong? Thanks!

Indeed. You'll want AsyncHTTPTransport.

See https://www.python-httpx.org/async/#explicit-transport-instances

Thanks Tom! Wasn't aware of AsyncHTTPTransport's existence.
Got HTTPTransport from https://www.python-httpx.org/advanced/#custom-transports
