mobile scroll command is not working in appium 1.5 for iOS application

Problem:-

I was using the following code to scroll to an element which is not visible.

WebElement element = driver.findElementByName("text");


JavascriptExecutor js = (JavascriptExecutor) driver;

HashMap scrollObjects = new HashMap();
scrollObjects.put("element", ((RemoteWebElement) element).getId());
js.executeScript("mobile: scrollTo", scrollObjects);

I am getting below error when I use above method for scrolling:-

Unknown command, all the mobile commands except scroll have been removed.

Solution:-

WebElement element = driver.findElementByName("text");

JavascriptExecutor js = (JavascriptExecutor) driver;

HashMap scrollObjects = new HashMap();
scrollObjects.put("element", ((RemoteWebElement) element).getId());
scrollObjects.put("direction", "down");
driver.executeScript("mobile: scroll", scrollObjects );
