Power BI Report Server - Upload (overwrite) existing Excel File
Hello, we are using the Power BI Report Server (May 2020). We have saved some Excel-Files on Power BI Report Server (Upload). We are able to upload the Excel-File but we are not able to overwrite the existing Excel-File. When we want to upload the same Excel-File again we are asked whether the existing file should be overwritten. If we click "overwrite" the following message occures (Internal error on Reportserver): In the Logfie I can find the following message: "System.InvalidOperationException: Das Objekt mit Nullwert muss einen Wert haben..|" (Nullable Object must have a value) Does anyone has the same error? Is this a bug in PBIRS Version May 2020? Thank you. Kind regards NiHi
