ValueError: Parsed code is not active.

[TiesToetToet]

Wanneer ik de volgende code run:

from zermelo import Client

cl = Client("rls")

token = cl.authenticate("mijn code")
print(token["access_token"])

Krijg ik:

Traceback (most recent call last):
  File "c:\Users\user\Documents\Python\github\python\Zermelo\zermelo-google.py", line 6, in <module>
    print(cl.authenticate("mijn code"))
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\user\AppData\Local\Programs\Python\Python311\Lib\site-packages\zermelo\client.py", line 28, in authenticate
    raise ValueError("Parsed code is not active.")
ValueError: Parsed code is not active.

Hoe kan ik dit verhelpen?
