When I run katalon test cases am getting this below error always " Test Cases/Start page FAILED because (of) (Stack trace: com.kms.katalon.core.exception.StepFailedException: Unable to wait for object to be present (Root cause: java.lang.IllegalArgumentException: Object is null)"
Please doublecheck, if the test object does exist in Object repository and if its properties are filled correctly. Optionally, you can paste a screenshot of Test Object settings here.
