Error: The host is experiencing an AttributeError because the 'Service' object does not have the attribute 'process' available

Looking to scrape a website using Python on a host without GUI. Unfortunately, the webpage I want to scrape ( ) does not allow scraping with the requests library, so I have to resort to using Selenium with a headless webdriver. (Apologies for any language errors!)

Here's the code I ran on a cPanel host via terminal:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from time import sleep
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options

chrome_options = Options()  
chrome_options.add_argument("--headless")
with Chrome(options=chrome_options) as driver:
    driver.get("https://aqms.doe.ir/App/")
    sleep(10)
    refresh = driver.find_element(By.XPATH, '/html/body/app-root/app-toolbar/div/div/app-toolbar-port/mat-toolbar/mat-toolbar-row[1]/button[2]/span/mat-icon')
    refresh.click()
    sleep(10)
    shn = driver.find_element(By.CSS_SELECTOR, '#highcharts-29 > div > div:nth-child(1) > span > div > span:nth-child(1)').text
    print(shn)

NOTES:

I have installed Selenium on the host using the terminal. and the chromewebdriver.exe is in the same folder as the code file (both the source and chromedriver are located in one folder). I executed this code by creating an application in cPanel using 'setup python' and running it in the terminal.

However, I encountered this Error:

File "req2.py", line 10, in <module>
    with Chrome(options=chrome_options) as driver:
File "/home/gigachad/virtualenv/python_bot/3.8/lib/python3.8/site-packages/selenium/webdriver/chrome/webdriver.py", line 81, in __init__
    super().init(
File "/home/gigachad/virtualenv/python_bot/3.8/lib/python3.8/site-packages/selenium/webdriver/chromium/webdriver.py", line 103, in init__
    self.service.start()
File "/home/gigachad/virtualenv/python_bot/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 106, in start
    self.assert_process_still_running()
File "/home/gigachad/virtualenv/python_bot/3.8/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 117, in assert_process_still_running
    return_code = self.process.poll()
AttributeError: 'Service' object has no attribute 'process'

I believe this error might be due to the way it was run on the host.

Thank you!

To utilize the Chrome driver in Selenium, you must provide a Service object as an argument to Chrome(). This service should point to the installation location of the chromedriver binary object.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from time import sleep
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

chrome_options = Options()  
chrome_options.add_argument("--headless")
with Chrome(service=Service(ChromeDriverManager().install()), options=chrome_options) as driver:
    driver.get("https://aqms.doe.ir/App/")
    sleep(10)
    refresh = driver.find_element(By.XPATH, '/html/body/app-root/app-toolbar/div/div/app-toolbar-port/mat-toolbar/mat-toolbar-row[1]/button[2]/span/mat-icon')
    refresh.click()
    sleep(10)
    shn = driver.find_element(By.CSS_SELECTOR, '#highcharts-29 > div > div:nth-child(1) > span > div > span:nth-child(1)').text
    print (shn)
