Inconsistently getting "Exception has occurred: JavascriptException" error selenium

Question

Hello something really weird happening I’m getting
"Exception has occurred: JavascriptException / Message: javascript error: this.each is not a function" on this specific line:

waiting.until(EC.visibility_of_element_located((By.CLASS_NAME, "xxxx")))

it does work half of the time but at the other half gives this error

Code:

from selenium import webdriver
import time
import requests
from cgitb import text
from unittest import result
from bs4 import BeautifulSoup
from selenium.webdriver.common.by import By
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver.get("https://steamcommunity.com/market/listings/730/M4A4%20%7C%20Mainframe%20%28Minimal%20Wear%29")

waiting = WebDriverWait(driver, 10)
waiting.until(EC.visibility_of_element_located((By.CLASS_NAME, "csgofloat-itemfloat")))

page_source = driver.page_source
soup = BeautifulSoup(page_source, "html.parser")
hopefully_floats = soup.find_all("div", {"class": "csgofloat-itemfloat"})

time.sleep(15)
print(hopefully_floats)
print(type(hopefully_floats))
driver.quit()

Answer 1

You are missing a driver initialization, something like

driver = webdriver.Chrome(service=webdriver_service, options=options)

And opening a link, something like

driver.get(url)

This is one way to achieve your end goal (or what I understand from it). First, make sure that extension is installed, and check its exact location. Then you can do something like this:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


import time as t

chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument('--load-extension=/home/user/.config/chromium/Default/Extensions/jjicbefpemnphinccgikpdaagjebbnhg/2.4.3_0') ## extension location on your filesystem

chrome_options.add_argument("window-size=1280,720")

webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
wait = WebDriverWait(browser, 20)
url = 'https://steamcommunity.com/market/listings/730/M4A4%20%7C%20Mainframe%20%28Minimal%20Wear%29'
browser.get(url)
t.sleep(2)
float_vals = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'div[class="float-div"]')))
for f in float_vals:
    float_value = f.find_element(By.CSS_SELECTOR, 'div[class="csgofloat-itemfloat"]')
    paint_seed = f.find_element(By.CSS_SELECTOR, 'div[class="csgofloat-itemseed"]')
    print(float_value.text, paint_seed.text)

Result:
