MISTAKE. Selenium, Facebook WebDriver, PHP. What is the problem?

Question

Facebook

Good afternoon! I'm trying to figure out with selenium.
I use: selenium-server-standalone-3.9.1 and Facebook WebDriver.
When executing this code, everything is fine. Google page opens in chrome.

<?php
namespace Facebook\WebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
require_once('vendor/autoload.php');
$host = 'http://localhost:4444/wd/hub';
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities);
$driver->get('https://www.google.com/');
print 'ok';
?>

But if we add the line:
$driver->findElement(WebDriverBy::xpath('*[@id="tsf"]/div[2]/div/div[3]/center/input[2]'))- >sendKeys('abc')->click();

<?php
namespace Facebook\WebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;
use Facebook\WebDriver\Remote\RemoteWebDriver;
require_once('vendor/autoload.php');
$host = 'http://localhost:4444/wd/hub';
$capabilities = DesiredCapabilities::chrome();
$driver = RemoteWebDriver::create($host, $capabilities);
$driver->get('https://www.google.com/');
$driver->findElement(WebDriverBy::xpath('*[@id="tsf"]/div[2]/div/div[3]/center/input[2]'))->sendKeys('abc')->click();
print 'ok';
?>

It throws an error like this:

Fatal error: Uncaught Facebook\WebDriver\Exception\NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"*[@id="tsf"]/div[2]/ div/div[3]/center/input[2]"} (Session info: chrome=75.0.3770.80) For documentation on this error, please visit: http://seleniumhq.or...ch_element.htmlBuild info: version: '3.9.1', revision: '63f7b50', time: '2018-02-07T22:42:28.403Z' System info: host: 'OBR-PC', ip: '192.168.100.104', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_211' Driver info: driver.version: unknown in C:\xampp\htdocs\ vendor\facebook\webdriver\lib\Exception\WebDriverException.php:102 Stack trace: #0 C:\xampp\htdocs\vendor\facebook\webdriver\lib\Remote\HttpCommandExecutor.php(326): Facebook\WebDriver\Exception\ WebDriverException::throwException(7, 'no such element...', Array) #1 C:\xampp\htdocs\vendor\facebook\webdriver\lib\Remote\RemoteWebDriver.php(547): Facebook\WebDriver\Remote\ HttpCommandExecutor->execute(Object(Facebook\WebD in [/size] C:\xampp\htdocs\vendor\facebook\webdriver\lib\Exception\WebDriverException.php on line [/size]102

Tell me what to do, yesterday I spent the whole day looking for a solution, but I didn’t figure it out (( I used this article
as a guide .

Good afternoon. Everything is simple. You most likely have the wrong xpath selector.
Try instead
Write like this:
//body/*
You will get all the elements inside the body tag. And there, one step at a time, go to your element.
