Web Data Connector
Option 1If the Web Data Connector you are using was created internally, it may need to be updated to support changes to the WDC web browser engine in Tableau 2019.4. Specifically, changes may be needed to ensure that data is transmitted and inserted into the extract in smaller chunks. For more information see: Get Data - Best Practices. If the WDC was not created by you, follow up with the publisher of the WDC.
Option 2As a workaround, use Tableau Desktop and Server 2019.3 or earlier. Click here for downloads of current and previous versions of Tableau Desktop and Server: Tableau Desktop Downloads and Release Notes, Tableau Server Downloads and Release Notes. For more information on current releases, see Upgrade Tableau Desktop and Desktop Upgrade, Upgrade Tableau Server and Server Upgrade.
CauseThe internal web browser engine for Web Data Connectors was updated in Tableau 2019.4 and contains a limitation in its data communication channel where a single transmission of data cannot exceed approximately 128mb. See WDC News for more information.
