When a third map is added to a dashboard and that dashboard is published to Tableau Server, the view fails to load and throws an exception:
"An unexpected error occurred. If you continue to receive this error please contact your Tableau Server Administrator. 
Session ID: [SESSION ID]
Tableau Server (Version [VERSION]) encountered an error while working with this worksheet.
Would you like to reset the view?"


  • Tableau Server 10.2.2-10.2.4, 10.3.2
  • Windows Server 2012
  • Tableau Data Engine


As a Tableau Server Administrator, upgrade to Tableau Server 10.2.5, 10.3.3 or a later version. For more information, see Upgrading Tableau Server in Tableau Help.


Adding more than two maps to a view causes VizQL Server to crash in older version of Tableau Server.
