    Tableau Prep InputNodeFailureException "with error code 2"

    Mark Hardcastle

      I created a Tableau Prep flow that runs a handful of queries pulling from Microsoft SQL Server databases, does some basic cleaning and aggregation, and unions them together. It has worked perfectly for a couple of days, but now when I run it I get the following error message:



      When I click into each of the steps, including the union step that is immediately before the output step, they run just fine. A screenshot of the flow follows:



      Removing the 5 leftmost steps--those that start with "Locum"--causes the flow to work. Yesterday the flow output without error, with all of the steps included.


      Has anybody else encountered this error code? Thanks in advance!
