Warning "This Version of the Web Data Connector Library is Deprecated"

Issue

When connecting to your data using a WDC (Web Data Connector), the following error occurs:
 
"This Version of the Web Data Connector Library is Deprecated"
 
 

Environment

  • Tableau Desktop 2019.1 and newer versions
  • Tableau Server 2019.1 and newer versions
  • Tableau Online
  • WDC libraries 1.x, 2.0.0 and 2.0.1 

Resolution

If you are a user of a Web Data Connector and received a warning message, contact the developer of the connector directly.
 
If you are a developer of a Web Data Connector, update your connector to use one of the supported libraries. See WDC Versions and refer to Upgrading from WDC Version 1.x for the steps to migrate from version 1.x.



 

Cause

The earlier versions of the Web Data Connector client library were not designed for use under Qt WebEngine. Therefore, Tableau will no longer support these versions in future releases.
The following versions of the Web Data Connector client library (tableauwdc-x.x.x.js) are deprecated starting in Tableau 2019.1 and will not be supported in later releases:

  • 1.x (all versions)
  • 2.0.0
  • 2.0.1

Additional Information

Web Data Connectors are JavaScript-based components written by third-party developers to build data connectors for Tableau. Web Data Connectors use an internal browser in Tableau called Qt WebKit. In the next Tableau release (after Tableau 2019.1), Web Data Connector will use Qt WebEngine (a Chromium-based browser), a significant upgrade over Tableau’s current browser. WDC developers will benefit from this upgrade with the ability to use modern JavaScript, and Chrome developer tools for debugging WDC code.
 
The earlier versions of the Web Data Connector client library were not designed for use under Qt WebEngine. Therefore, Tableau will no longer support these versions in future releases.
 
To find the latest version of the Web Data Connector client library, see WDC Versions.
