Hi, @ST3 ;

1.First started with dataflow. refresh the dataflow.
2. Then  create a report using only dataflow.
3. Checked the gateway connections.

4.Re-enter the datasource credentials which may be fix the error.

"When i do it manually it works"

Please elaborate.  Are you referring to Power Query in a Power BI Desktop ?
