Dear All,

Can anyone please help me to configure Machine learning extractor while using document understanding. I am getting this error :- This version of the DocumentUnderstanding.ML package is incompatible with UiPath.PDF.Activities older than v3.15.0 and UiPath.IntelligentOCR.Activities older than v6.10.0. Please update the conflicting packages.

I could not see the invoices as value under ML skill dropdown which is mandatory field to fill.

Also Please note i am using the public endpoint for invoices for western europe (germany) from this site:- [Document Understanding - Public Endpoints (uipath.com)](https://docs.uipath.com/document-understanding/automation-cloud/latest/user-guide/public-endpoints)
