Getting org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value' while running the script on mobile browser

Question

I am using:

1. selenium 3.0.0
2. Appium : 1.7.2

Requirement: Scroll in the mobile browser and click the button which will open new url.

Code:

Point loc =Driver.findElement(By.xpath("//div[@id='button']")).getLocation(); 

System.out.println(loc);
JavascriptExecutor js = (JavascriptExecutor)Driver;
js.executeScript("javascript:window.scrollBy(0,"+loc.y+")"); 
Thread.sleep(4000);
//Actions actions = new Actions(Driver);
//actions.sendKeys(Keys.PAGE_UP).perform();
Driver.findElement(By.xpath(//div[@id='button']")).click();

Getting exception:

org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value' at this line : js.executeScript("javascript:window.scrollBy(0,"+loc.y+")");

Note: but element is scrolled to that point
