Troubleshooting
Problem
In Rule Designer 8.9.2.1, when selecting the menu Decision Center \ Connect to synchronize my project to Decision Center, the Decision Center configuration wizard does not open. It seems nothing happens.
In Rule Designer workspace .log, we can see the following IllegalArgumentException:
