how to pass empty string to a input element in katalon studio

Question

I am doing automating the test cases for my web page using Katalon Studio. My problem is that I don't know how to pass or send an empty string to an input element, here I want my test case to fail so. I tried with set text and sendkeys keywords, getting following error

TC_2_testcase_for_fail-Copy FAILED because (of) (Stack trace: groovy.lang.MissingPropertyException: No such property: WebUiBuiltInKeywords for class: Script1539673712359 at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:53) at org.codehaus.groovy.runtime.callsite.PogoGetPropertySite.getProperty(PogoGetPropertySite.java:52) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGroovyObjectGetProperty(AbstractCallSite.java:307) at Script1539673712359.run(Script1539673712359.groovy:33) at com.kms.katalon.core.main.ScriptEngine.run(ScriptEngine.java:183) at com.kms.katalon.core.main.ScriptEngine.runScriptAsRawText(ScriptEngine.java:108) at com.kms.katalon.core.main.TestCaseExecutor.runScript(TestCaseExecutor.java:294) at com.kms.katalon.core.main.TestCaseExecutor.doExecute(TestCaseExecutor.java:285) at com.kms.katalon.core.main.TestCaseExecutor.processExecutionPhase(TestCaseExecutor.java:264) at com.kms.katalon.core.main.TestCaseExecutor.accessMainPhase(TestCaseExecutor.java:256) at com.kms.katalon.core.main.TestCaseExecutor.execute(TestCaseExecutor.java:200) at com.kms.katalon.core.main.TestCaseMain.runTestCase(TestCaseMain.java:99) at com.kms.katalon.core.main.TestCaseMain.runTestCase(TestCaseMain.java:90) at com.kms.katalon.core.main.TestCaseMain$runTestCase$0.call(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:149) at TempTestCase1539675610128.run(TempTestCase1539675610128.groovy:22) at groovy.lang.GroovyShell.runScriptOrMainOrTestOrRunnable(GroovyShell.java:263) at groovy.lang.GroovyShell.run(GroovyShell.java:518) at groovy.lang.GroovyShell.run(GroovyShell.java:507) at groovy.ui.GroovyMain.processOnce(GroovyMain.java:653) at groovy.ui.GroovyMain.run(GroovyMain.java:384) at groovy.ui.GroovyMain.process(GroovyMain.java:370) at groovy.ui.GroovyMain.processArgs(GroovyMain.java:129) at groovy.ui.GroovyMain.main(GroovyMain.java:109) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.codehaus.groovy.tools.GroovyStarter.rootLoader(GroovyStarter.java:109) at org.codehaus.groovy.tools.GroovyStarter.main(GroovyStarter.java:131) )

Simple, just send the empty string as a parameter:

WebUI.setText(findTestObject('Object Repository/input element'), '')
