Connection using the SharePy library

Connection using the SharePy library

Abi Winters 25

Hi,

I have been using the SharePy python library to interact with my Sharepoint access for some time. As of last week, without any changes to either the Sharepoint, the account permissions, or my code, I suddenly started getting the following error when attempting to connect.

import sharepy
sharepy.connect("sitename", username="username", password="password")

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/[username]/.local/lib/python3.11/site-packages/sharepy/session.py", line 15, in connect
    return SharePointSession(site, auth=autoauth)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/[username]/.local/lib/python3.11/site-packages/sharepy/session.py", line 61, in __init__
    self.auth.login(self.site)
  File "/home/[username]/.local/lib/python3.11/site-packages/sharepy/auth/spol.py", line 26, in login
    self._get_cookie()
  File "/home/[username]/.local/lib/python3.11/site-packages/sharepy/auth/spol.py", line 60, in _get_cookie
    cookie = self._buildcookie(response.cookies)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/[username]/.local/lib/python3.11/site-packages/sharepy/auth/spol.py", line 91, in _buildcookie
    return 'rtFa=' + cookies['rtFa'] + '; FedAuth=' + cookies['FedAuth']
                     ~~~~~~~^^^^^^^^
  File "/home/[username]/.local/lib/python3.11/site-packages/requests/cookies.py", line 334, in __getitem__
    return self._find_no_duplicates(name)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/[username]/.local/lib/python3.11/site-packages/requests/cookies.py", line 413, in _find_no_duplicates
    raise KeyError(f"name={name!r}, domain={domain!r}, path={path!r}")
KeyError: "name='rtFa', domain=None, path=None"

Has anyone encountered something similar?

Thanks.

Hi @Abi Winters ,

This might be because Microsoft is starting to disable basic authentication: Basic authentication is being deprecated (SharePoint Server) - SharePoint Server | Microsoft Learn

And I don't think you are the only one experiencing this, as the same issue was brought up in SharePy repository as well : Sharepy auth key error when accessing cookies dictionary · Issue #83 · JonathanHolvey/sharepy

I suggest using other supported methods of authentication at this point. Consider reaching out to with tags like Microsoft 365 and Office | SharePoint | Development or Microsoft 365 and Office | SharePoint Server | For business for better help.

Best Regards.

Hi,

Thanks for your response, unfortunately neither of the links you included resolved to a valid webpage, would it be possible for you to try posting them again please?

Do you know if this will effect the broader Sharepoint APIs? The current documentation I can find on the Microsoft portal about Sharepoint API is from 2023, so if it's in the middle of changing I will have to wait for that to be updating before planning future changes on my end.

Thanks again.

My bad for the links, they were formatted funkily but they should be working now.

As for your query, SharePoint API itself isn't being retired, so your existing APIs should still be working.
I suggest checking this tag Microsoft 365 and Office SharePoint Development - Microsoft Q&A for better directed support.Hope this helps
