JWT in session file not honored

[higgins]

Thank you for this SDK!

It looks like either the jwt that is saved in the session_file I provide is either invalid or I'm instantiating something wrong.

Here's what I'm doing:

1. If session_file exists, parse it for the jwt and pass that and session_file to duolingo.Duolingo instantiation. Explicitly setting password=None
2. I get this error:

Traceback (most recent call last):
  File "test_duolingo", line 25, in <module>
    lingo  = duolingo.Duolingo(username, password=None, jwt=jwt, session_file=session_file)
  File "/usr/local/lib/python3.9/site-packages/duolingo.py", line 66, in __init__
    self._login()
  File "/usr/local/lib/python3.9/site-packages/duolingo.py", line 112, in _login
    raise DuolingoException("Login failed")
duolingo.DuolingoException: Login failed

The SDK works perfectly fine if I use username/password each time I instantiate Duolingo

Here is the code:

import sys
import json
from pathlib import Path
import duolingo

username = "[REDACTED]"
password = "[REDACTED]"
session_file = "/some/absolute/path"

session = Path(session_file)
if session.is_file():
    print("\033[95mUsing DuoLingo session...\033[0m")
    file = open(session_file, "r")
    jwt = json.load(file).get("jwt_session")
    lingo  = duolingo.Duolingo(username, password=None, jwt=jwt, session_file=session_file)
else:
    print("\033[95mLogging into DuoLingo...\033[0m")
    lingo  = duolingo.Duolingo(username, password, session_file=session_file)
