for the past two days I have been trying to find out why the Send to Tableau Server node didn’t work anymore. I was getting the following error message: Execute failed: Server Response Code: 400.
I had changed my Tableau password, and also changed it in the node in my workflow. In the end I worked out that it was the & in my new password that was causing the problem. Changed my password to something not containing & and it worked again, changed it back to a password containing & and I got the same error.
(Using KNIME 3.6.2, KNIME Tableau integration 3.6.0.v201805031009)
