Summary
When running a Server/Gallery workflow with a Publish to Tableau Server tool, it may throw an error about incorrect filename or directory. The workflow runs fine in Designer on the local machine. This is a known defect attributed to AMP Engine behavior. A fix has been developed.
Description

When running workflow in Server, the workflow results show the following error with the Publish to Tableau Tool:

  
Error opening the file "Tool #227: \ProgramData\Alteryx\Engine\Engine_... .hyper": The filename, directory name, or volume label syntax is incorrect. (123)
Environment
  • Alteryx Server
    • Version 2022.1
  • Tableau Server
    • All
  • Publish to Tableau Server Tool
  • AMP Engine enabled on workflow
  • Workflow runs fine in Designer on the local machine
  • Output file is created and uploaded to Tableau successfully, despite the error
Cause

This is a known product defect (TDSL-4435) that is related to the behavior of the AMP Engine when the workflow runs in Server. 

A fix has been developed for Alteryx Server 2022.3+.

    Resolution

    Solution A - Upgrade the Alteryx server to 2022.3 (or higher).

    Solution B - Use the Tableau Output tool in place of the Publish to Tableau Server tool

    1. Download and install the Tableau Output tool
    2. Open the workflow in Designer and replace the Publish to Tableau Server tool with the newer Tableau Output tool. The Publish to Tableau Server tool has been deprecated, so we recommend switching over to the Tableau Output tool
    3. Publish the edited workflow to Server

    Solution C - Disable AMP Engine on the workflow

    1. Open the workflow in Designer
    2. Click on an empty space in the canvas
    3. In the Workflow - Configuration pane on the left, click on Runtime, then uncheck "Use AMP Engine"

    4. Save the workflow and publish it to Server
    Note: We recommend disabling the AMP Engine on the workflow as a temporary workaround rather than a permanent solution, because doing so removes the benefits of the AMP Engine.
