Hello,

I tried the PickerSample App without any code changes, to get familiar with the Microsoft Graph SDK. Only I registered an application ID on azure portal and entered it into variable ONEDRIVE_APP_ID.
Starting the app is possible, but whatever I click on the start screen, I get the message

Contents of the console window as follows:
