I'm trying to use selenium to automate some actions but am unable to find the first element on the page https://developer.servicenow.com/dev.do and so cannot login

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver_path = "../bin/chromedriver.exe"
driver = webdriver.Chrome(driver_path)

driver.get("https://developer.servicenow.com/dev.do")

driver.find_element_by_xpath("/html/body/dps-app//div/header/dps-navigation-header//header/div/div[2]/ul/li[3]/dps-login//div/dps-button//button/span")

I get the error

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/dps-app//div/header/dps-navigation-header//header/div/div[2]/ul/li[3]/dps-login//div/dps-button//button/span"}

To Sign In button is deep within multiple #shadow-root (open)

shadow-root-open-multiple

Solution

Tto click() on the desired element you can use shadowRoot.querySelector() and you can use the following Locator Strategy:

from selenium import webdriver

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://developer.servicenow.com/dev.do')
SignInButton = driver.execute_script("return document.querySelector('dps-app').shadowRoot.querySelector('dps-navigation-header').shadowRoot.querySelector('header.dps-navigation-header dps-login').shadowRoot.querySelector('dps-button')")
SignInButton.click()
  • Browser Snapshot:

shadow-root-open

I think its because you are trying to access the "Sign in" before the website has time to load all of the elements.

I suggest you use

driver.set_page_load_timeout(120)

so the selenium will look for the button after everything is loaded on the website.
