External user in sharepoint site unable to get auth token

[markprovenioai]

Good day,

I have the following error: ValueError: Acquire token failed: An error occurred while retrieving auth cookies from https://<externalCompany>.sharepoint.com/_forms/default.aspx?wa=wsignin1.0.

I am from myCompany and were given full access to https://<externalCompany>.sharepoint.com/sites/ABC/SitePages/Home.aspx.

So my code is shared below.

import json
from office365.runtime.auth.user_credential import UserCredential
from office365.runtime.http.request_options import RequestOptions
from office365.sharepoint.client_context import ClientContext

username = "[email protected]"
password = "securepassword"
site_url = "https://<externalCompany>.sharepoint.com/sites/ABC"

ctx = ClientContext(site_url).with_credentials(UserCredential(username, password))
request = RequestOptions("{0}/_api/web/lists/GetByTitle('Documents')/items?$select=FileLeafRef,FileRef".format(site_url))
response = ctx.execute_request_direct(request)
json = json.loads(response.content)
files = json['d']['results']

for file in files:
    source = "https://" + site_url + file["FileRef"]
    # Check if item is file or folder
    check_request = RequestOptions("{}/_api/web/GetFolderByServerRelativeUrl('{}')"
                   .format(site_url, file["FileRef"]))
    folder = ctx.execute_request_direct(check_request).status_code == 200
    print(folder)
    print(source)

I was wondering is there API settings where this feature has been disabled? Is there a way for me to check? And can I give instructions to externalCompany to enable this feature? I cant find any documentation about it.

full error is below

Any update on this issue? We have been seeing the same error for a couple of weeks that has broken our application. I would help but I'm not sure how. I noticed that the post request to /_forms/default.aspx?wa=wsignin1.0 is no longer returning and 302 (its now 200) and it doesn't return any cookies either, and that causes it to break. Any known fixes, or at least what is causing it?

I am getting this error too. It is not a bug, it is probably a security configuration from the SharePoint tenant hosting the site.
