Katalon Error: Object is null

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)"

Can anyone please help?


Topic title updated.

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.

Yes, I have object in repository

In the image I also tried with double quotes for class. That also hasn’t work.

Are you sure you posted correct test step?
I can see “End action: waitForElementPresent” in the console and not click as on your screenshot.

Please provide a full test log.

This is the test case
This is the ouput.

Please neglect 10th step in test case. Please have look on remaining test cases.
