Power Bi Desktop - Error 2503 Graph Odata.Feed

Hi community, 

I'm refreshing my report and the following error appears. " OLE DB or ODBC error: [DataSource.NotFound] OData: Request failed (404): Remote server error: (404) Not found. (). 

The report connects to graph to retrieve the work shifts.

Do you know if the Odata-Feed data sources tied to Graph have changed or the URL construction has changed https://graph.microsoft.com/v1.0/teams/......./schedule/shifts 

?

Please help me.

All the best
