Schedule Refresh : sharepoint list and Cube datasource not working

Hi Community

I have  an issue with schedule Refresh on a PowerBI Report Server .

Actually, I am connecting my pbix to both two different data source : sharepoint list (url) and a cube (direct query)

I have creaed a scheduled refresh and I can see that it is finished wiht success = > Data REfresh completed

However, the data was not refresh :( I have to downlaod the file locally, refresh it manually and then deploy it on the server.

Is there a limitation of sharepoint list?

If yes why did not  receive an error message?

Is there any workarround ?

Any help will be appreciated.

Thanks and Regards

Asma
