How to address certificate verify failed: unable to get local issuer certificate error using Selenium and ChromeDriverManager

Question

Even with the ton of information about this, each solutions won't work for me, I'm trying to run a basic selenium script and I get this error. Is there any solutions for my case (note that i use 3.10 python and that I'm working on a corporate computer under windows OS which has Zscaler installed, if it is somehow usefull) Here is my code :

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

def openChrome():

    options= Options()
    options.add_experimental_option("detach", True)
    driverweb= webdriver.Chrome(service=Service(ChromeDriverManager().install()), options= options)
    driverweb.get('https://pypi.org/', verify=False)
    driverweb.set_window_size(1000,700)
    driverweb.set_window_position(0,0)

openChrome()

I tried to use the command (webdriver-manager update --ignore_ssl=true) but i think i use it the wrong way cause it is saying that webdreiver_manager isn't a command.

Here is the whole error i get :

Answer 1

get(url: str)

get(url: str) simply loads a web page in the current browser session and accepts only the url (string) as an argument. So if you try to pass the additional parameter verify=False that would result in an TypeError as:

TypeError: get() got an unexpected keyword argument 'verify'

verify=False is a valid parameter only for the Python Requests module. See details in GET and POST requests using Python.

This usecase

As a prerequisite you have to install webdriver-manager and removing the verify=False argument, your code executes perfectly on my windows-10 box.

• Code block:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  from selenium.webdriver.chrome.service import Service
  from webdriver_manager.chrome import ChromeDriverManager
  
  driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
  driver.get('https://pypi.org/')
  driver.set_window_size(1000,700)
  size = driver.get_window_size()
  print(size['height'], size['width'])
  driver.set_window_position(0,0)
  position = driver.get_window_position()
  print(position['x'], position['y'])
  

• Console output:
