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.

I had this issue as well. Until I converted String and V_String to V_WString, it worked fine. Thank you very much.

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.

Hi, thanks for posting this solution.  I was experiencing the same problem and this has helped.  When following step 1 (changing String or V_WString field types to V_WString), if there are many fields to update I have used a Multi-Field Formula tool to do this instead of using a Select tool.  Below is the configuration I used in case it helps others.

Hi I'm still getting this error even after converting all strings to V_WString and running Overwrite Existing Extract File (Create if does not Exist). I'm running Alteryx 2019.2 and would like to avoid updating due to server schedule transfers not working correctly.
