Office365-rest-python-client: AttributeError: 'ClientContext' object has no attribute '_auth_context'

Created on 7 Dec 2020 · 6Comments · Source: vgrem/Office365-REST-Python-Client

Currently using Office365-REST-Python-Client==2.3.0.1

When I run the following code:

def upload_to_sharepoint():
    url = 'https://tenant.sharepoint.com/sites/sitename'

    credentials = {
        'client_id': os.environ.get('client_id'),
        'client_secret': os.environ.get('client_secret'),
    }
    context_auth = AuthenticationContext(url=url)
    context_auth.acquire_token_for_app(client_id=credentials['client_id'],
                                       client_secret=credentials['client_secret'])
    ctx = ClientContext(url, context_auth)
    web = ctx.web
    ctx.load(web)

    file_name = f"vat check {datetime.now().strftime('%Y-%m-%d')}"
    path = os.path.join("/tmp", file_name)

    with open(path, 'rb') as content_file:
        file_content = content_file.read()

    list_title = "VAT Check"
    target_folder = ctx.web.lists.get_by_title(list_title).rootFolder
    # name = os.path.basename(path)
    target_file = target_folder.upload_file(file_name, file_content)
    ctx.execute_query()
    print(f"File url: {target_file.serverRelativeUrl}")

I get the following error, this seems like an error internally and not about the auth, or am I missing something?

AttributeError: 'ClientContext' object has no attribute '_auth_context'

That was fast, thanks @vgrem that solves the issue, tested it locally.

Greetings,

thank you for catching it! Turns out the instance of AuthenticationContext got lost when passing into ClientContext.

From another hand, since AuthenticationContext.acquire_token_for_app is considered as _deprecated_ nowadays, another option (_recommended_) would be to switch from:

context_auth = AuthenticationContext(url=url)
context_auth.acquire_token_for_app(client_id=credentials['client_id'],
                                       client_secret=credentials['client_secret'])
ctx = ClientContext(url, context_auth)

into

credentials = ClientCredential(credentials['client_id'], credentials['client_secret'])
ctx = ClientContext(settings['url']).with_credentials(credentials)

You probably need to update your package: pip install --upgrade Office365-REST-Python-Client @spurthikaribasaiah

Hi @erfannariman and @vgrem ,

I tried with above command. I am still getting the same issue.
Please find the code snippet below. I am using user credentials

pip install --upgrade pip
pip install Office365-REST-Python-Client
pip install --upgrade Office365-REST-Python-Client

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext

ctx_auth = AuthenticationContext(Sharepoint_SiteUrl)
ctx_auth.acquire_token_for_user(User, Pass)
ctx = ClientContext(Sharepoint_SiteUrl, ctx_auth)
web = ctx.web
ctx.load(web)
ctx.execute_query()
print("Authentication successful")
