Hi All,   So I have just gotten access to a Company Gateway and wanted to test setting up a dataflow. The query designer runs fine and there are no issues when validating the query.    However wh...

EDIT:  I tried to load the raw data without any extra step in the query (so no conditional columns). 

 

I tried this multiple times for different Excel files in my folder (which have the exact same columns and row data) and which load perfectly normal in desktop version when published => Somehow for some Excel files it randomly gives this exact same error.. And for some Excel files it doesn't..

 

It seems to be totally random and I have no idea why it's happening.. All of the data in the Excel files is exactly the same and it should make no difference at all..

 

I tried refreshing with 2 Excel files are in the folder => It works

I add 2 random excel files => Stops working..

I delete those 2 random excel files giving the error so that I just have those 2 original ones which were working => Stops working...

 

So this behaviour seems totally random and I don't know what is causing this..

 

This really seems like a bug..

Bumping to the top, I really don't understand this error and it seems to be a bug in my opinion..

    I'm using sharepoint folder as connector, in that also I'm getting same error in the dataflow.

     

    I've first created a code in Power BI Desktop, there the code was working perfectly, now I copy & pasted the code to my dataflow, and added credentials, but if I'm refreshing my dataflow, I'm getting same error.

     

    Error message: 

     

    Error: DataFormat.Error: We couldn't convert to Number. (.. RootActivityId = cf3a5bf9-106a-4c82-94bd-f855b92f7aca.Param1 = DataFormat.Error: We couldn't convert to Number. ( Request ID: ba9ff2ea-e988-49f3-8e85-a36235a6fc8f.

     

    Do anyone have an idea, why this kind of issue is happening

      I am getting the same error on one of my Data Flows and it is not only annoying, but dibilating for our work stream!   

       

      When I save the the workflow the query is validate fine, it is when I try to do the refresh it fails. 

       

      I have serveral business units that depend on this data flow with 12 tables in it and without it I would have to recreate several reports with their own version of the these 12 tables.   Please let me know how I solve this issue.

        Is there any resolutoin on this?   I now have 5 data flows that are failing for the same error, all of these ran fine and updated on schedule up until a few weeks ago.   Feels like another one of MS's poorly executed upgrades?
