I have now transferred my test processes for Sharpoint and Micorsoft 365 API from production to the test environment, as I had done initial tests on production.
I configured the BP Web API analogously and adjusted the IDs (tenant, client) and client secret accordingly.
On the test environment I get the following error message:
But our test user is registered on teams/ SharePoint and I can manually perform all actions (create, copy, etc. of files) with this test user on that site.
It is not clear why the test user should not have access to the site or the folder (403 error)? What could be the problem?
