directory creation and file upload to team and channel

[UNIcodeX]

I followed the instructions here to set up a client id and secret. https://github.com/vgrem/Office365-REST-Python-Client/wiki/How-to-connect-to-SharePoint-Online-and-and-SharePoint-2013-2016-2019-on-premises--with-app-principal

from office365.runtime.auth.client_credential import ClientCredential
from office365.runtime.auth.user_credential import UserCredential
from office365.sharepoint.client_context import ClientContext

client_id = ""
secret = ""
sharepoint_url = "https://{organization}.sharepoint.com/sites/Some Team"

def get_sharepoint_context_using_app():
    client_credentials = ClientCredential(client_id, secret)
    ctx = ClientContext(sharepoint_url).with_credentials(client_credentials)
    return ctx


def get_sharepoint_context_using_user():
    user_credentials = UserCredential(r"SvcAcctShareGate", r"%a$FotT583aJEwpx&8Cq")
    ctx = ClientContext(sharepoint_url).with_credentials(user_credentials)
    return ctx


def create_sharepoint_directory(dir_name: str):
    if dir_name:
        ctx = get_sharepoint_context_using_app()
        result = ctx.web.folders.add(f'Shared Documents/{dir_name}').execute_query()
        if result:
            # documents is titled as Shared Documents for relative URL in SP
            relative_url = f'Shared Documents/{dir_name}'
            return relative_url
        

def upload_to_sharepoint(dir_name: str, file_name: str):
    sp_relative_url = create_sharepoint_directory(dir_name)
    ctx = get_sharepoint_context_using_user()
    target_folder = ctx.web.get_folder_by_server_relative_url(sp_relative_url)
    with open(file_name, 'rb') as content_file:
        file_content = content_file.read()
        target_folder.upload_file(file_name, file_content).execute_query()


create_sharepoint_directory('test directory')

when the sharepoint_url is only https://{organization}.sharepoint.com I get :

office365.runtime.client_request_exception.ClientRequestException: ('-2130247139, Microsoft.SharePoint.SPException', '(null) "Shared Documents/test directory" not found.', "500 Server Error: Internal Server Error for url: https://{organization}.sharepoint.com/_api/Web/folders/Add('Shared%20Documents%2Ftest%20directory')")

when sites/Some Team is appended I get:

ValueError: {"error":"invalid_request","error_description":"AADSTS900023: Specified tenant identifier 'none' is neither a valid DNS name, nor a valid external domain.

What am I missing?
