Answer
I think you may set the scope in a wrong way. As far as I know, it should be https://yourSite.sharepoint.com/.default or detailed scope, such as: https://yourSite.sharepoint.com/Sites.ReadWrite.All
And now it is suggested to use Microsoft Graph API to manage your sharepoint site use Microsoft Graph API to manage your sharepoint site.
It provides a unified programmability model that you can use to access the tremendous amount of data in Office 365, Windows 10, and Enterprise Mobility + Security.
