Why test case is stopped even if FailureHandling.CONTINUE_ON_FAILURE is used


I don’t understand why test case is stopped whereas I use FailureHandling_CONTINUE_ON_FAILURE into caller.

Code into caller:

switch (testCaseName) {
	case testCaseName:
		WebUI.callTestCase(findTestCase(testCaseName), param, FailureHandling.CONTINUE_ON_FAILURE)

Error into callee:

This error occured into test case called with WebUI.callTestCase(...)

Caused by: com.kms.katalon.core.webui.exception.WebElementNotFoundException: Web element with id: ‘XXX’ located by ‘By.xpath: XXX’]’ not found

But, if I use FailureHandling_CONTINUE_ON_FAILURE so callee must be stopped, but not caller right?

Thanks for help
