WebElement Not Found Error

[theautomater33]

Hello,

I am new on Katalon, and searched the forum little bit but could not find a solution. On my project, I have captured the xpath manually such as “//*[@id=“memberSearch”]” . Later tried with AbsoluteXpath.
However, I am getting an error as " Xpath is null" and my test fails. Later I wanted to try the new Self-Healing mode. I captured all the elements by using the spy mode. Every attempt to heal the element location also had failed. This element takes a little time to load inside a widget. I am using Katalon 7.6.1.

Any help will be appreciated.

" Xpath is null"

This message is odd.

I have ever seen this message only once 2 years ago in a very old version Katalon Studio:

Cannot find elements when XPath expression is null

I have made a project on GitHub, where you can reproduce the insident. https://github.com/kazurayam/Cannot_find_elements_when_XPath_expression_is_null OS: Mac OS 10.13.6 High Siearra Katalon Studio: version 5.7.1 How to reporoduce the insident git clone this project or download ZIP form the relases page. open the project with Katalon Studio v5.7.0 or higher. open Test Caset/TC1 and execute it. The source is as follows: import static com.kms.katalon.core.testobject.ObjectRepository.findTe…

The problem was fixed already. The same problem has revived in Katalon 7.6.1 ? — not likely.

Could you show the fill log where you saw “Xpath is null” ?

[theautomater33]

I guess that error displays during execution. As I see now it shows the element cannot be located/found. I have tried to run the script until the widget is loaded with WebUI.waitForElementPresent(findTestObject(‘Object Repository/Dashboard/lookUpParticipantInputBox’), 5), but no luck.

Here is the log file

WebUI.waitForElementPresent(findTestObject(‘Object Repository/Dashboard/lookUpParticipantInputBox’), 5), but no luck.

I can not see why because sufficient information not yet provided. Please have a look at the following guideline.

• [TIP] How To Help Us Help You!

we would require full HTML page source, Test Object defintion, your test case script, and execution log. It is nice if the URL of your target web application is public and accessible for us,

[theautomater33]

I am working on my company’s internal web application. Please see the screenshots I have:

Xpath for search Button:

Xpath for searchTextBox:

Script:

SpyMode Capture textbox:

SpyMode Capture LookUpButton:

[kazurayam]

Your HTML is simple enough. Your TestObjects seem to be OK. You showed just a part of test case script. I can not see if it is OK or not.

In the execution log, I could not find a log how your script navigated to the target URL. Possibly the Chrome browser is opened, but the test case script seems to be navigating to nowhere Does the test case script open the web page? Does you test case script include the lines like this ?

WebUI.openBrowser('')
WebUI.navigateToUrl('https://my.little.website')     // <-- do you have this ?
WebUI.verifyElementPresent(findTestObject('Object Repository/Dashboard/lookupParticipantInputBox'), 10)

I guess you are looking at a white empty screen because your script lacks a line of WebUI.navitateToUrl(...)

[theautomater33]

Well I am storing the website url in global variable then navigating. I have to login at the beginning. Everything works until I come to the widget after login. Then xpath cannot be found.

[kazurayam]

I can not find any more thing. I would give up, sorry.

[theautomater33]

Thanks for spending time to help. I hope someone can point out why Katalon errors out in this scenario.

[theautomater33]

I have actually tried to delay for a while. Later realized the widget is using JQuery. I used
WebUI.waitForJQueryLoad(20). Then I am getting an error : “This website don’t use jQuery.”
Still trying different approaches.

[anuradha]

Hello @theautomater33, is it possible that the step you need before clicking on the button is not happening. you can check in your reports what is happening in the screenshots/videos.

Thanks

[theautomater33]

A wise man once said Katalon might not be able to capture, but Javascript will never be broken.

So here is the solution for someone who may have the same issue in the future:

  String js1="document.getElementById('participantSearch').value = " +GlobalVariable.memberId;

   WebElement element = WebUiCommonHelper.findWebElement(findTestObject('Your object'),20)

  WebUI.executeJavaScript(js1 , Arrays.asList(element))

Do not forget
import org.openqa.selenium.WebElement as WebElement
import com.kms.katalon.core.webui.common.WebUiCommonHelper as WebUiCommonHelper
