Instagram login script with selenium, not being able to execute .send_keys('test')

Ok so, as the title says, pretty much i just cant make my python program work, it is a bot to log in to instagram and it wont actually do the logging in part, i've tried both using action chains, and without them, this is my code (python 3.6.1) : 

from time import sleep
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

browser = webdriver.Chrome()
browser.get('https://www.instragram.com')

login_elem = browser.find_element_by_xpath('//*[@id="react-root"]/section/main/article/div[2]/div[2]/p/a')
login_elem.click()

user = browser.find_element_by_name("username")

passw = browser.find_element_by_name('password')

ActionChains(browser)\
    .move_to_element(user).click()\
    .send_keys('test')\
    .move_to_element(passw).click()\
    .send_keys('test')\
    .perform()

login_button = browser.find_element_by_class_name(
'_0mzm- sqdOP  L3NKy       ')


login_button.click()

Pretty simple, right? and at since there are no syntax errors, i truly am confused over what is going wrong, since once I run my code, nothing happens after going to the login page. (Which means, it's not actually actuating on the username and password forms)

This is what the Module says :

Traceback (most recent call last): File "C:\Users\ferna\Desktop\trying browser script.py", line 17, in .send_keys('test')\ File "C:\Users\ferna\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\action_chains.py", line 83, in perform action() File "C:\Users\ferna\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\common\action_chains.py", line 277, in Command.MOVE_TO, {'element': to_element.id})) File "C:\Users\ferna\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute self.error_handler.check_response(response) File "C:\Users\ferna\AppData\Local\Programs\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document (Session info: chrome=71.0.3578.98) (Driver info: chromedriver=2.45.615291 (ec3682e3c9061c10f26ea9e5cdcf3c53f3f74387),platform=Windows NT 10.0.17134 x86_64)

Was Selenium not install properly? or is the error inside my code? I would really appreciate any help I can get. Btw: I'm finding the username and password elements by name and not xpath, since Instagram changes the xpath and selector every time the page is opened, making the elements quite hard to find in other ways, at least with my very limited experience.

Solution

  • it works with my code, if it's helpful please accept it.


    1 add a expected_conditions wait util the actual login page appear

    
second_page_flag = wait.until(EC.presence_of_element_located(
    (By.CLASS_NAME, "KPnG0")))  # util login page appear


    2 change the xpath selector syntax here 

    login_button_ = browser.find_element_by_xpath(
    "//form[@class='HmktE']/div[3]/button")


login_button_.click()


    the all codes here:

    from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait

browser = webdriver.Chrome()
browser.get('https://www.instragram.com')

wait = WebDriverWait(browser, 10)

login_elem = browser.find_element_by_xpath(
   '//*[@id="react-root"]/section/main/article/div[2]/div[2]/p/a')

second_page_flag = wait.until(EC.presence_of_element_located(
    (By.CLASS_NAME, "KPnG0")))  # util login page appear


user = browser.find_element_by_name("username")

passw = browser.find_element_by_name('password')

ActionChains(browser)\
    .move_to_element(user).click()\
    .send_keys('test')\
    .move_to_element(passw).click()\
    .send_keys('test')\
    .perform()

login_button_ = browser.find_element_by_xpath(
    "//form[@class='HmktE']/div[3]/button")

login_button_.click()
