TypeError on Python 3.13.0a5

[killjoy1221]

I was playing around with httpx in Python 3.13 and keep getting this error. It works in 3.12, so I'm not sure if it's a bug in httpx or 3.13's urllib.

$ pipx list | grep httpx
   package httpx 0.27.0, installed using Python 3.13.0a5
    - httpx
 
$ httpx http://localhost

It was a bug in python, and it was fixed last month.
