I have resolved the issue. This is coming when there is space in one of my global variable in the end. Like var = "abc " instead of var=“abc” ---

This `joptsimple.IllegalOptionSpecificationException` can be caused by a “$” character too, as documented (rather poorly) here: [https://docs.katalon.com/katalon-studio/docs/troubleshoot-globalvariable-special-character.html](https://docs.katalon.com/katalon-studio/docs/troubleshoot-globalvariable-special-character.html) The issue is, there is a “$” character in either: 1. The variable’s name 2. The variable’s value So this GlobalVariable would give you a double headache: ![image](https://europe1.discourse-cdn.com/katalon/original/2X/c/c0d58bf08c5bcb242c099caf380141fe2a7eb8e2.png) Thanks to @ThanhTo and @devalex88 for their combined efforts to help find the source of this error.
