getting below while running test case in selenium webdriver.

java.lang.RuntimeException: java.lang.NullPointerException
	at ru.yandex.qatools.ashot.util.InnerScript.execute(InnerScript.java:29)
	at ru.yandex.qatools.ashot.shooting.ViewportPastingDecorator.getFullHeight(ViewportPastingDecorator.java:67)
	at ru.yandex.qatools.ashot.shooting.ViewportPastingDecorator.getScreenshot(ViewportPastingDecorator.java:41)
	at ru.yandex.qatools.ashot.shooting.ViewportPastingDecorator.getScreenshot(ViewportPastingDecorator.java:35)
	at ru.yandex.qatools.ashot.AShot.takeScreenshot(AShot.java:143)
	at selenium.org.sample.SampleProject.Screenshot.ScreenshotPage.ScreenshotPage1(ScreenshotPage.java:14)



below is my class to of screenshot
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import ru.yandex.qatools.ashot.AShot;
import ru.yandex.qatools.ashot.Screenshot;
import ru.yandex.qatools.ashot.shooting.ShootingStrategies;
import selenium.org.sample.SampleProject.TestBase.TestBase;

public class ScreenshotPage extends TestBase
{
	 public void ScreenshotPage1() throws InterruptedException, IOException
	{ 
		Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
	    ImageIO.write(fpScreenshot.getImage(),"PNG",new File("D:/selenium/"+System.currentTimeMillis()+".png"));
	 }
}


and below I am calling method of screenshotPage class.

import java.io.IOException;
import org.openqa.selenium.support.PageFactory;
import org.testng.Assert;
import org.testng.annotations.Test;
import selenium.org.sample.SampleProject.UIAction.SignIn;
import selenium.org.sample.SampleProject.ExcelReader.ExcelReader;
import selenium.org.sample.SampleProject.Screenshot.ScreenshotPage;

public class AppTest extends ExcelReader
{
	@Test(dataProvider="testdata")
	public void Log(String email,String pwd) throws IOException, InterruptedException
	{
		ScreenshotPage S=new ScreenshotPage();
		System.out.println("Sign in page");
		SignIn loginpage = PageFactory.initElements(driver, SignIn.class);
		 loginpage.setUserName(email); // Enter username
		 loginpage.setPwd(pwd); // Enter password
		 Thread.sleep(8000);
		 S.ScreenshotPage1();//calling method from ScreenshotPage class 
		 loginpage.Sign_In_btn();// Submit button click
		 driver.manage().window().maximize();
		 try
		 {
		Assert.assertEquals(driver.getTitle(),"My account - My Store");
	     System.out.println("Log  IN successfull1");
		 }
		 catch(AssertionError E)
		 {
			 System.out.println("Log  IN un-successfull"+E);
		 }
		 Thread.sleep(8000);
		S.ScreenshotPage1();	 
	} 


What I have tried:

below code is running successfully facing this issue only when calling method.

import java.io.IOException;
import org.openqa.selenium.support.PageFactory;
import org.testng.Assert;
import org.testng.annotations.Test;
import selenium.org.sample.SampleProject.UIAction.SignIn;
import selenium.org.sample.SampleProject.ExcelReader.ExcelReader;
import selenium.org.sample.SampleProject.Screenshot.ScreenshotPage;

public class AppTest extends ExcelReader
{
	@Test(dataProvider="testdata")
	public void Log(String email,String pwd) throws IOException, InterruptedException
	{
		ScreenshotPage S=new ScreenshotPage();
		System.out.println("Sign in page");
		SignIn loginpage = PageFactory.initElements(driver, SignIn.class);
		 loginpage.setUserName(email);// Enter username
		 loginpage.setPwd(pwd);// enter password
		 Thread.sleep(8000);
		Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
	     ImageIO.write(fpScreenshot.getImage(),"PNG",new File("D:/selenium/"+System.currentTimeMillis()+".png"));

		loginpage.Sign_In_btn();// clicks button
		 driver.manage().window().maximize();
		 try
		 {
		Assert.assertEquals(driver.getTitle(),"My account - My Store");
	     System.out.println("Log  IN successfull1");
	
		 }
		 catch(AssertionError E)
		 {
			 System.out.println("Log  IN un-successfull"+E);
		 }
		 Thread.sleep(8000);
		S.ScreenshotPage1();
	}

The error message clearly states that the error occurs on line 29 of Innerscript.java. Where is that code?

The variable driver is nowhere defined and initialised in your code.

It is in TestBase and Screenshot Page extends TestBase.

And is it properly initialised there?
