    Error on incremental refresh: No such function isnull that takes arguments of type (datetime).

    Marco Suess

      Hello Tableau Community!

       

      I am developing a WDC (GitHub - meltwater/tableau-web-data-connector: Meltwater Web Data Connector for Tableau). I'm implementing incremental refresh and the increment column id is a datetime column. The refresh works fine in the simulator in Chrome, but when I try it in Tableau Desktop I get the following error:

       

      • No such function isnull that takes arguments of type (datetime).
      • Unable to create extract

       

      Unfortunately, the Tableau WDC Debugger crashes when I try this so I am unable to obtain further details on the error.

       

      Do you guys have any experience with this error?
