Dataflow: unexpected error



I tried the new Dataflow functionality but regardless of which source I use I keep on receiving an unexpected error.

Somebody knows what to do?

Hi @VSchepens,


Please update your on-premise data gateway to the latest version 3000.0.144.3 then test again.

Hi @v-qiuyu-msft,


We are even on a higher version: 3000.0.155.1 but it still doesn't work.






Hi @VSchepens,


Please ensure you have entered the correct user name and password for SQL data source. 


Instead of creating corresponding for gateway during the time you create a data low entity, you can also go to Manage Gateways create the SQL data source firstly, then create a data flow entity and choose this gateway to see if the same issue occurs.

Hi, curious if this issue was ever resovled.  I tried different data sources as well, even the 'Blank table' and still received the 'Unexpected error' window with a Session ID and Request ID.  Below that is a text box lable "Mashup text' and text box value = "Failed to get mashup text from server."


Has anyone encountered this issues?


Thank you,

To @VSchepens and @sd_kevin : did you try with workspaces "new style" ?
