Scenario: We want to download files from our company sharepoint using an API, which uses the client credentials flow. No users involved. We do this to fetch help files and content for our apps.
Issue: Since this weekend, whenever we want to download files from Sharepoint, a non specific BadRequest exception occurs.
Text: {"error":{"code":"invalidRequest","innerError":{"code":"badArgument"},"message":"One of the provided arguments is not acceptable."}}
It does not specify which arguments aren't acceptable.
The production code generates the request via the Graph API framework, using
Temporary download also contains the same error,

This doesn't work at all.
We can't find a work around.
ApiVersion=2.0
