Hi @Kolb, Jannik
This may be an issue with the API, I just confirmed this with my colleague. Since last week, the $filter
query parameter for drive items doesn't seem to work.
I suggest you submit a support ticket with the Microsoft Support team to confirm if there are any changes to the API.
Hope this helps.
