[Python] Why can't I log into duolingo-api in python with duolingo.Duolingo('username',...

I'm trying to access my duolingo data via scripting, and found duolingo-api. https://pypi.org/project/duolingo-api/ https://github.com/KartikTalwar/Duolingo

I followed their installtion and usage directions in the documentation, but consistently get the same error when trying to log in.

This post seemed promising, but I couldn't figure out how to apply it to my case. Login into Duolingo using Python Requests

install via bash: $ pip install duolingo-api

python script:

import duolingo
lingo = duolingo.Duolingo('kartik', 'my password')


the error:

Traceback (most recent call last):
File "/home/"<my-current-directory>"/duolingo/lib64/python3.11/site-packages/requests/models.py", line 974, in json
return complexjson.loads(self.text, **kwargs)

During handling of the above exception, another exception occurred:

I tried analyzing the error and the source code, but being new to python and web requests, I couldn't make sense of it. I have also tried installing globally, and in a virtual environment, on a slackware, arch and 2 windows machines with the same result. I can't find any information on this package online other than its own documentation, and can't figure out what to do. Any help would be greatly appreciated. Thank you!
