[FIXED] Can't add any items to cart on bestbuy.ca but bestbuy.com works?

Issue

I've been trying to learn how to add items to my cart on BestBuy.ca. Unfortunately, whenever I attempt to add an item to my cart I get the following error:

However, on the American version of the site, the exact same code (only modified classname) succeeds at adding items to the cart. Anyone know why this is happening?

Canadian site code:

from selenium import webdriver
import time

PATH = "C:/webdrivers/chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://www.bestbuy.ca/en-ca/product/glue-loca-liquid-for-smart-phone-top-glass-lcd-screen-repairing-50g-optical-clear/10754680")

buyButton = driver.find_element_by_class_name("addToCartButton")
buyButton.click()

time.sleep(20)

American site code:

from selenium import webdriver
import time

PATH = "C:/webdrivers/chromedriver.exe"
driver = webdriver.Chrome(PATH)
driver.get("https://www.bestbuy.com/site/artscase-tempered-glass-screen-protector-for-apple-iphone-12-pro-max-clear/6442159.p?skuId=6442159")

##Will ask which bestbuy site if you're not American so added 10s sleep to select the American site.
time.sleep(10)

buyButton = driver.find_element_by_class_name("add-to-cart-button")
buyButton.click()

time.sleep(20)

Solution

There is a bot detection feature based on navigator.webdriver. You have to hide it using a chrome option, so that the site doesn't detect that the browser is started by an automation process.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

import time

PATH = "C:/webdrivers/chromedriver.exe"

options = Options()
options.add_argument('--disable-blink-features=AutomationControlled')

driver = webdriver.Chrome(PATH,options=options)
driver.get("https://www.bestbuy.com/site/artscase-tempered-glass-screen-protector-for-apple-iphone-12-pro-max-clear/6442159.p?skuId=6442159")

##Will ask which bestbuy site if you're not American so added 10s sleep to select the American site.
time.sleep(10)

buyButton = driver.find_element_by_class_name("add-to-cart-button")
buyButton.click()

time.sleep(20)

Without the chrome option flag:

With the chrome option flag:
