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 :

Answers:
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.
