Dataflow - error when refreshing

Hi all,

I'm getting an error when I try to refresh one of my dataflows. This is the only one (of 5 total) dataflow in this workspace that is getting an error.

 

When I download the csv file, all it says is:

 

Error: Request ID: f8103593-4397-1edb-c3e5-71d3ed08620f Activity ID: 057ead59-16f3-4a77-b863-c3d21c11499b

 

Nothing seems to work to get it refreshed, it's very frustrating. It keeps giving an error exactly on 31 seconds refresh time.

 

Please help, thanks.

Nobody?

 

I've tracked the error down to a single step in my dataflow.

I got 3 tables that I merge into one new table. I then untick the 'load data' option for the 3 tables.

When I use table.combine( table1 ) everything works fine. When I try to merge more than 1 table by table.combine( table1, table2 ) I get the error.

 

It works whether I load table1, table2 or table3. As long as it's only a single table.

 

I've tried recreating a whole new dataflow: same error. Other workspace: same error. This is driving me crazy.

 

To be clear, I have another dataflow that is EXACTLY the same, but with 3 slightly different tables. That one works fine with table.combine( table1, table2, table3 )
