Error "The Hyper file is corrupt and needs to be re-created"When Viewing a Published Workbook

Issue

When viewing a published view or workbook on Tableau Online, the following error might occur:

“Unable to connect to the data source.
Try connecting again. If the problem persists, disconnet from the data source and contact the data source owner
(...)The Hyper file is corrupt and needs to be re-created”.

Environment

Tableau Online

Resolution

The extracts used by that view or workbook need to be re-created. Please follow one of the two options below

Option 1 - Issue a full refresh on Tableau Online

If possible, try to issue a full refresh of the extracts by following this steps:

Navigate to the published workbook (or published data-source) on Tableau Online and click on the “…” button (called More actions) located next to the Download icon.
From the drop-down menu, select Refresh Extracts… to issue a refresh

Option 2 - Locally re-creating the extract and re-publishing the workbook to Tableau Online

Alternatively, the error can be resolved by re-creating the extracts locally:

Download and open the workbook in Tableau Desktop
Re-create the extract on Tableau Desktop by selecting Data > (Extract Name) > Extract Data from the menu, and selecting Extract on the dialog showing up.
Re-publish the workbook (or data-source) to Tableau Online.

Cause

This error is shown whenever the current extract data differs from the last time the extract was created or refreshed. Such differences may occur due to a variety of reasons, such as problems with unreliable hard disks, thumb drives or network transfers (e.g., when publishing to Tableau Online).

Additional Information

While such errors are only detected for extracts created by Tableau versions 10.5 or later, re-creating the extracts on any version of Tableau should resolve the error.
