Facing "Authorization header token missing user information" error when using api.partner.microsoft.com

Hi,

Im having issues to query

https://api.partner.microsoft.com/v1.0/payouts/transactionhistory

Where Im getting HTTP 400 with a quite generic error message: Authorization header token missing user information

My current workflow:

1. obtain access token using client_secret

using https://login.microsoftonline.com/{{tenant}}/oauth2/token

client_id:<CLIENT_ID>
client_secret:<CLIENT_ID_SECRET>
grant_type:client_credentials
resource:https://api.partner.microsoft.com

2. query https://api.partner.microsoft.com/v1.0/payouts/transactionhistory using the access token obtained in the previous step.

Thank you for your help in advance.
