Issue

When attempting to download data from a published view whose name, or whose workbook name, contains a non-alphanumeric character, the following error may occur:

LogicException: Internal Error - An unexpected error occurred and the operation could not be completed.

Environment

  • Tableau Online 2018.1
  • Tableau Server 2018.1

Resolution

Option 1

As a Tableau Server Administrator, upgrade to Tableau Server . For more information, see Upgrading Tableau Server in Tableau Help. 

Option 2

As a workaround, republish the workbook and ensure that neither the view name, nor the workbook name, contains any non-alphanumeric characters (such as +).

Cause

An issue in Tableau Online and Tableau Server prevented data downloads from succeeding when the view or workbook contained a non-alphanumeric character. This behavior is related to a known issue (ID: 773171) which has been fixed in a recent release of Tableau Server.
