It appears that there is no element for the given statement. Therefore, it is important to include a check for null before using the sendKeys method.

WebElement el = driver.findElement(By.xpath(".//*[@id='question 14998']/div/textarea"));
if (el != null) {
  el.sendKeys("What is the top website for learning JAVA?");
} else {
//Perform some other actions 
}

Hey there! Give this code a try with a slight tweak and see if it fixes the issue:

 public static void main(String[] args) throws Exception  {
            WebDriver driver = new FirefoxDriver();
            driver.manage().timeouts().implicitlyWait(700, TimeUnit.SECONDS);
            driver.get("https://getinsights.co");
            driver.manage().window().maximize();

        //Login//
        driver.findElement(By.xpath("html/body/div[1]/div/nav/div/div[2]/ul/li[7]/a")).click();

        //Login_page//
        driver.findElement(By.xpath("//*[@id='form']/div[1]/input")).sendKeys("<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="394d5c4a4d5e5c4d50574a505e514d795e54585055175a5654">[email protected]</a>");
        driver.findElement(By.xpath("html/body/div[1]/div/div[2]/div/form/div[2]/input")).sendKeys("airloyal");
        driver.findElement(By.xpath("html/body/div[1]/div/div[2]/div/form/div[3]/div[2]/button")).click();

        //Create_survey//
        Thread.sleep(10000);

        System.out.println("driver=" + driver);
        driver.findElement(By.xpath("//*[@placeholder='Type your Question']")).sendKeys("Which is the best website to learn JAVA?"); 
 // Null pointer Exception //here i simply changed the xpath and its working 
        driver.findElement(By.xpath("//*[@id='rootId']/div/div/div[2]/div[2]/div[1]/div[5]/button")).click();

        //Post_Question
        driver.findElement(By.cssSelector(".clear.openTextStyle.ng-pristine.ng-untouched.ng-invalid.ng-invalid-required")).sendKeys("Java");

        driver.findElement(By.cssSelector(".launch-btn.ng-binding")).click();

        driver.quit();

After completing the final steps, make sure to utilize the following code snippet:

  driver.quit();
  driver.close();

Using driver.quit() will close all browsers and destroy the session, so adding driver.close() will result in a null pointer exception. It's important not to include any selenium webdriver code after using driver.quit(). If you need to use both commands, follow this sequence:

  driver.close();
  driver.quit();
