Hi.
We have a web service that returns a JSON file. I wish to validate the text in the JSON files.
I set up a Katalon test object for the web request.
I test the request and it returns the correct values.
I wish to verify this web request’s text with this simple test case…
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS
//'Send a SOAP request and returns its response'
def response = WS.sendRequest(findTestObject('PSTD/PSTD-01_01'))
//'Verify converted weight after sending request is correct or not'
WS.verifyElementText(response, 'abcxyz123', '3000')
But I receive this error…

The web request returns a null object. Why?
I thought perhaps its something to do with log4j. So I install these libraries.
And I add the following…
import org.apache.log4j.PropertyConfigurator
Properties log4jProp = new Properties();
log4jProp.setProperty("log4j.rootLogger", "WARN");
PropertyConfigurator.configure(log4jProp);
This solves the issues with log4j. But the main error remains.
Perhaps the issue is the Verification tab in the web request object? It is empty, but I’m not sure what it does.
