I having an issue getting direct query mode working for SQL Server on Power BI Report Server (August 2017 Preview) My query is really simple "SELECT data, u from GBT3". The table has 2 rows If I create a report using import mode it works in Power BI Desktop, Power BI Service (via the gateway) and Power BI Report server If I create a report using direct query it works in Power BI Desktop, Power BI Service (via the gateway), but NOT on Power BI Report server On Power BI Report server I get: Something went wrong Unable to load the model Please try again later or contact support. If you contact support, please provide these details.
