Unable to take screenshot of CEF application using Selenium - selenium

Question

I am using Selenium to automate the CEF application. I am successfully able to perform operations like click etc. But not able to take the screenshot using Selenium driver. As it is very much required feature for automation. How can I do this?
I'm using the following:
CEF application - sample application provided by CEF
selenium jar - selenium-server-standalone-3.0.1
cef_binary_3.2924.1564.g0ba0378_windows64_client
chromedriver
Find the below code:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.OutputType;
public class Example {
public static void main(String[] args) {
// Path to the ChromeDriver executable.
System.setProperty("webdriver.chrome.driver", "D:/CEFTesting/chromedriver.exe");
// Path to the CEF executable.
ChromeOptions options = new ChromeOptions();
options.setBinary("D:/CEFTesting/cef_binary_3.2924.1564.g0ba0378_windows64_client/Release/cefclient.exe");
WebDriver driver = new ChromeDriver(options);
driver.get("http://www.google.com/xhtml");
sleep(3000); // Let the user actually see something!
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("ChromeDriver");
searchBox.submit();
sleep(5000); // Let the user actually see something!
String screenshotBase64 = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BASE64);
System.out.println(screenshotBase64);
sleep(5000); // Let the user actually see something!
driver.quit();
}
}
I am facing the error.
