Hi @Vivek

So I tried to google the exception and it seems that, to get it working you have to add some arguments to the Chrome Web Driver.

> <https://stackoverflow.com/questions/50642308/webdriverexception-unknown-error-devtoolsactiveport-file-doesnt-exist-while-t/50725918#50725918>

In your test case’s script mode, you can try to initiate ChromeDriver with the above options, as demonstrated in this documentation.

[https://docs.katalon.com/katalon-studio/tutorials/using\_selenium\_webdriver\_katalon\_studio.html#options-and-capabilities](https://docs.katalon.com/katalon-studio/tutorials/using_selenium_webdriver_katalon_studio.html#options-and-capabilities)

So your script may start with something like this:

```auto
import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions
import com.kms.katalon.core.webui.driver.DriverFactory

ChromeOptions options = new ChromeOptions()
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
WebDriver driver = new ChromeDriver(options)

```

Please try and see if this workaround resolves the situation.

Regards !

I have created a custom keyword  
public class chromeBrowser {  
@Keyword

```
def OpenBrowser(String url) {

	System.setProperty("webdriver.chrome.driver","/usr/local/bin/chromedriver");

	ChromeOptions options = new ChromeOptions();

	options.addArguments("–no-sandbox");

	options.addArguments("–disable-dev-shm-usage");

	options.setExperimentalOption("useAutomationExtension", false);

	WebDriver driver = new ChromeDriver(options); 
	 		
	DriverFactory.changeWebDriver(driver);

	driver.get(url);
}

```

}

**and now i am getting**

Hi @Vivek

I see the exception is telling you that your custom keyword class cannot be found. In your script have you followed the following method to use custom keywords ?

[https://docs.katalon.com/katalon-studio/tutorials/create\_custom\_keyword.html#custom-keywords-in-scripting-view](https://docs.katalon.com/katalon-studio/tutorials/create_custom_keyword.html#custom-keywords-in-scripting-view)

Hi @Vivek

I notice that in your script, this line only has a single dash:

> [@Vivek](#):
>
> `options.addArguments("–no-sandbox");`

While the argument referred from the StackOverlflow post contains double dash:

> [@ThanhTo](#):
>
> `options.addArguments("--no-sandbox");`

Could you see if adding the dash into this line (as well as other lines) resolves the issue ?

Thanks !

Hi @Vivek

From this StackOverflow answer:

> <https://stackoverflow.com/questions/50027278/message-unknown-error-chrome-failed-to-start-exited-abnormally-on-aws-cloud9/50027645#50027645>

I think it’s because of compatibility between ChromeDriver and Chrome browser. Could you try upgrading and the solutions proposed by the StackOverflow answer ?

Regards !

Hi @ThanhTo

This got fixed just using by removing this line of code “DriverFactory.changeWebDriver(driver);”

public class chromeBrowser {  
@Keyword

```
def OpenBrowser(String url) {

	System.setProperty("webdriver.chrome.driver","/usr/local/bin/chromedriver");
	ChromeOptions options = new ChromeOptions();
	options.addArguments("--no-sandbox");
	options.add_argument("--disable-dev-shm-usage");
	options.setExperimentalOption("useAutomationExtension", false);
	WebDriver driver = new ChromeDriver(options);
	driver.get(url);
}

```

}

Thanks a lot  
🙂

Hi @Vivek

Nice to see you got it fixed. Could you mark your own answer as solution so that others will have an easier time fixing this issue ?

Hi vivek !  
Kindly please tell me that you have used a method add\_argument("–disable-dev-shm-usage") is it true?  
addArguments or add\_argument ?  
for me both are not working.
