Error "The file was not uploaded successfully" Publishing to Tableau Online Using Alteryx

Issue

When Publishing to Tableau Online from Alteryx since 11/19/2020, the following error occurs in Alteryx:

The file was not uploaded successfully

Environment

Tableau Online
Alteryx

Resolution

See the Alteryx article Publish to Tableau tool Error: The File was not Uploaded successfully for full steps and screenshots.

1. Open the workflow in question that is showing error. Right-click the Publish to Tableau Server tool and select "Open Macro". This will open the workflow which is the Tableau Connector tool itself.

2. Go to Edit > Find, type in "257" and select Filter tool #257.

3. In that Filter tool update the Custom filter entry to:

findString([DownloadHeaders],"HTTP/1.1 201")>=0

Cause

Alteryx is using the response text rather than the response code. The API response was changed for Tableau Online from "201 Created" to "201".

Additional Information

Note: You should not rely on specific text appearing in the <detail> element of an error response. Instead, test the value of the error code attribute to determine why an operation failed.
