InvalidArgumentException: Message: invalid argument: user data directory is already in use, please specify a unique value error while opening website

I'm trying to open a website in my default browser with selenium but I can get it to work.

My code:

import time
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import Select

options = webdriver.ChromeOptions() 
options.add_argument("user-data-dir=C:\\\\Users\\rober\\AppData\\Local\\Google\\Chrome\\User Data")
driver = webdriver.Chrome(executable_path="C:\\\\Users\\rober\\OneDrive\\Skrivebord\\Bot\\chromedriver.exe", chrome_options=options)

driver.get("https://www.zalando.dk/jordan-air-jordan-1-mid-sneakers-high-joc12n001-a18.html")

buyButton = False

while buyButton is False:

    try:
        
        addToCartBtn = addButton = driver.find_element_by_xpath('/html/body/div[4]/div/div[2]/div/div/div[2]/div[1]/x-wrapper-re-1-6/div/div[4]/button')

        print("Varen er udsolgt")

        time.sleep(1)
        driver.refresh()

    except:
        addToCartBtn = addButton = driver.find_element_by_xpath('//*[@id="picker-trigger"]')

        print("Varen er på Lager")
        buyButton = True

while buyButton is True:
    time.sleep(1)
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.uc-btn#uc-btn-accept-banner"))).click()
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Vælg størrelse']"))).click()
    driver.execute_script("return arguments[0].scrollIntoView(true);", WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//label[starts-with(@for, 'size-picker')]//span[text()='51.5']"))))
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//label[starts-with(@for, 'size-picker')]//span[text()='51.5']"))).click()
    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Læg i indkøbskurv']"))).click()
    WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'a[title="Indkøbskurv"]'))).click()
    WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".z-coast-base__totals-tile .z-1-button__content"))).click()
    WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'a[title="Registrér dig"]'))).click()

My Error:

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

I think the error has something to do with \ but I can not figure it out.

Hope someone can help

This error message...

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session for either of the following reasons:

  • There are previous instance of ChromeDriver process attached to the system memory.
  • You have a manually opened session already running.

You need to initiate the execution of your program with a clean slate.

Further, while working with Selenium v3.x, ChromeDriver and on you may need to pass the argument executable_path along with the absolute path of the ChromeDriver binary through either of the following options:

  • Double back slashes i.e. (\\)
  • Single back slash i.e (\) along with the raw (r) switch.
  • Binary extension i.e. (.exe)

So you have to change the line :

driver = webdriver.Chrome(executable_path="C:\\\\Users\\rober\\OneDrive\\Skrivebord\\Bot\\chromedriver.exe", chrome_options=options)

with :

driver = webdriver.Chrome(executable_path=r'C:\Users\rober\\OneDrive\Skrivebord\\Bot\chromedriver.exe', options=options)

or :

driver = webdriver.Chrome(executable_path="C:\\Users\\rober\\OneDrive\\Skrivebord\\Bot\\chromedriver.exe", options=options)
