I installed the Tableau extension, and configured the dependancies as per instructions in the node description (PATH system configuration and Visual C++ 2013 redistributable instalation). I’m working with Hyper as my Tableau Server version is 2019.1 I also restarted many times the KNIME Analytics Platform.
However, when i execute the “Send to Tableau Server (Hyper)” Node I get this error message: ERROR Send to Tableau Server (Hyper) 0:370 Execute failed: Unable to initialize Tableau backend ‘Tableau Hyper’, please follow the installation instructions in the node description. Error:java.lang.UnsatisfiedLinkError: Unable to load library ‘TableauHyperExtract’: No se puede encontrar el módulo especificado.
Thanks for your support. Already tried all of these, as you suggest:
Verify all Tableau extensions are well installed
Restart KNIME via File -> Restart
Verify that the PATH points to the Hyper library and not to the TDE
Still, the error shown is the same: Execute failed: Unable to initialize Tableau backend ‘Tableau Hyper’, please follow the installation instructions in the node description. Error:java.lang.NoClassDefFoundError: Could not initialize class com.tableausoftware.hyperextract.ExtractAPI
Here’s my printed screen that shows the “Linked Resources” and “Environment Variable PATH”.
