The following error occurs on REFRESH of a Tableau Workbook (TWB):
java.lang.RuntimeException: Error happens when downloading reduced workbook for 15
The error occurs when the Tableau Workbook uses a live data source (TDE). Due to limitations in the Tableau SDK, only a Tableau Workbook that uses an extract data source can be refreshed via InfoBurst.
This issue has been reported to Tableau development. This forum will be updated if a fix for this issue is released.
