I have Tableau 2018.1.3 running on a Centos 7 EC2 instance. When my coworker tries to connect from his Tableau Desktop (version 10.5 but also tried version 2018.1.3) I get the following error from the vizportal log:
catalina-exec-6 vizportal: ERROR com.tableausoftware.api.clientxml.ClientXmlHandshakeController - java.lang.NumberFormatException: For input string: "null"
java.lang.NumberFormatException: For input string: "null"
When searching for others who've had this issue I've only seen results related to Tabjolt which we don't have set up. It's like vizportal is expecting some value that it's not getting. Has anyone encountered this error outside the realm of Tabjolt?
