Error Uploading File - Extra data in JSON ???

[UNIcodeX]

Getting the error talked about here (https://github.com/vgrem/Office365-REST-Python-Client/issues/547). Discussion on this seems to be dead.

      If you do not have a certificate, one can be created using the following command in powershell:

      openssl req -newkey rsa:2048 -new -nodes -x509 -days 999999 -keyout key.pem -out cert.pem

      Upload the resultant .pem file on Azure AD manager under your App Registration's  "Certificates & secrets", and then the "Certificates" tab.
