PBI report using Oracle database as data source

Hello guys!

I am in face in some issue with PBI report using a Oracle database as data source.

Basically, I’ve created a report connected on Oracle database using PBI Desktop, I can work with this report with PBI Desktop, but after publish this report I am not able to see the report using PBI Service (with My Workspace). I got an error message: “Couldn't load the model schema. See details”

Please, take a look the screenshots below.

Thanks in advance!
