I'm learning on the Graph API as a whole and to access Sharepoint in particular. I figured out how to authenticate with the help of the ADAL library for Python. I can access my sharpeoint site. I can get a list of all the lists of the site. But somehow when I ask for the items in a list, I get nothing. In Graph Explorer, I get each lines.
Any idea what might be wrong? I don't understand how I can access the site and get to the list without any problem, but the items does not show up. I also have no error. I only get a "value" :  answer, will the usuall context stuff.
It can't get any stupider than that. Your first question did it. I assigned all the permissions I needed (delegated) in Azure Portal, to my app, including the one you mention. However I didn't press "grant". So they were not really effectives I guess. Still doesn't understand why I had some but not others. But now it works. I get the items.
Thanks for pointing me out to the obvious :) Looks like I needed it to resolve my "issue".
