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
