### Question
What is Stale Element Reference Exception?

### Answer
This Exception occurs when driver is trying to perform action on the element which is no longer exists in DOM or not valid.

WebElement ele = driver.findElement(By.id(""sample""));

// Before clicking some thing happened and DOM has changed due to page refresh, or element is removed and re-added

ele.click();

Now at this point, the element which you're trying to click is no longer valid then selenium throws StaleElementReferenceException
