    Unexpected Server Error: "Required parameter modified missing or invalid; value is null."

      Hello,

       

      We are running the latest version of Tableau Server and one of our users recently received this error when they tried opening a when trying to open a workbook (see attached for screenshot):

       

      Unexpected Server Error: "Required parameter modified missing or invalid; value is null."

       

      I've never seen this error before, has anyone else? The workbook's data source is a cube.

       

      Cheers,

      Jon
