Error When Exporting to Tableau Hyper File Type

Hello. I am using Designer 2018.1 and have a legacy workflow that successfully exports to a .tde (Tableau Data Extract).

I have converted my Tableau workbook to use a .hyper extract instead and would therefore like to export directly to .hyper file with the output tool.

However, my legacy Alteryx workflow experiences the following error when exporting (output tool to .hyper file type).

Error: Designer x64: The Designer x64 reported: InboundNamedPipe::ReadFile: Not enough bytes read. The pipe has been ended.

I am still able to export with a .tde in the workflow below and can also export to .hyper for other 'from scratch' Alteryx workflows. This appears to be an issue only with my legacy Alteryx workflow.

As a follow-up, the solution is to change all text fields to V_WString.

if you have multiple text fields to convert to V_WString, you can use the 'Multi-Field Formula' and convert them all at once instead of manually using the 'Select Tool'.

Here's an image of my setup.

I'm seeing the same behavior in several of my workflows as well. All I changed was the Publish to Tableau tool and set to Hyper. If I change the publish to tableau tool back to TDE from Hyper it runs without error.

We are also seeing this error using the Publish to Tableau Server Macro when trying to publish to .HYPER file type. Works fine when publishing to .TDE
