Hi MOVC 

 

Thanks for using Microsoft Fabric Community.

Apologies for the inconvenience that you are facing here.

When using Microsoft Fabric Dataflow Gen2 with an on-premises data gateway, you might encounter issues with the dataflow refresh process. The underlying problem occurs when the gateway is unable to connect to the dataflow staging Lakehouse in order to read the data before copying it to the desired data destination. This issue can occur regardless of the type of data destination being used.

To troubleshoot the issue kindly refer to the documentation for details.

 

I hope this informatoin helps. Please do let us know if you have any further questions.

 

Thanks.

    Thank you for the reply, but I am able to create new gen 2 dataflows copying data via the gateway to warehouse in new workspaces without issue so I don't believe that this is the problem.

      Further testing:

       

      If I create a new Warehouse and a new Dataflow gen2 in the same workspace as the original version, then I get the same error message. However if I use a brand new workspace with the same dataflow query and a new warehouse then it works. 

      Could there be an issue with the Staging Lakehouse in that Workspace?

        Hi

        Please go ahead and raise a support ticket so an engineer can take a closer look at this situation.

        If you've isolated the issue to a particular workspace, then this would require an investigation by our support ticket.
