Selenium Webdriver python headless does not identify elements

Question

Good afternoon, I am programming a python file using Lenium. I reached my goal and the file ran smoothly. I went further and decided to use the headless, already at the beginning of the file execution I get an error:

in check_response raise exception_class(message, screen, stacktrace) Selenium.common.exceptions.Nosuchelementexception: Message: no such element: Unable to locate element: {"method":"css selector","selector":". whsOnd zHQkBf"} (Session info: headless Chrome=86.0.4240.198)**

Indicating that he was not able to identify the element on the page, only that this error persists also when trying to use the selector xpath, class, full xpath and id.

My code:

from time import sleep
from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--headless")
driver = webdriver.Chrome(chrome_options=options, executable_path='C:/Users/Thunder/drivers/chromedriver.exe')
driver.get('https://classroom.google.com/u/1/c/MTIzNzc4MTM2NjY5')
sleep(8)
logan = driver.find_element_by_id('identifierId')
logan.send_keys('e-mail')
logan.send_keys(u'\ue007')

Hello! To further specify my comment I will post what I imagine to be the answer, so I saw in your code you did not import Chrome options, I imagine that only solves your problem:

from selenium.webdriver.chrome.options import Options

If that doesn’t solve try to put that line of code in place of your 4°line:

option = Options()
option.headless = True

If the problem is the headless will run straight, because from what I understand the code worked only that when you went to use the headless did not work anymore
