I can't get the sales report via API

Hello! I want to get a sales report using the API. I do everything as specified in the documentation at this link
https://learn.microsoft.com/en-us/windows/uwp/monetize/acquisitions-data

I receive the access token successfully, but when I try to get the report I get the error

{"data":null,"errors":[{"code":"Unauthorized","message":"Authentication Exception.","trackingId":"320799ce-627c-47ba-95f7-af752af454e9"}],"statusCode":0}
