I'm studying web scraping.
I'm trying to get a list of Starbucks coffee stores (name + address).

As shown below, scraping is not prohibited in robots.txt.
User-Agent: *

Starbucks HP uses Javascript, and all stores are not displayed unless you click the "More" button.
So I used selenium and used the .click () function to try to display all items.

However, as detailed below, I get a WebDriverException.
I would appreciate it if anyone could give me some advice if you know how to deal with it.
Thank you very much.

import requests
import time
import csv
import pandas as pd
from selenium import webdriver
from selenium.common.exceptions import ElementNotInteractableException
from bs4 import BeautifulSoup
Launch #Chrome headless and get Starbucks HP
options = webdriver.ChromeOptions ()
options.add_argument ('--no-sandbox')
options.add_argument ('--headless')
options.add_argument ('--disable-dev-shm-usage')
driver = webdriver.Chrome (options = options)
time.sleep (1)
html = driver.page_source
soup = BeautifulSoup (html,'lxml')
#Click the "more" button until the end
while True:
    try: try:
        more_btn = driver.find_element_by_xpath ('// * [@ id = "moreList"]')
        more_btn.click ()
        time.sleep (1)
    except ElementNotInteractableException:

#Get the store list
detailContainers = soup.find_all ('div', class_ = "detailContainer")
storeNames = []
storeAddresses = []
for detailContainer in detailContainers:
    storeNames + = [detailContainer.find (class_ ='storeName'). get_text ()]
    storeAddresses + = [detailContainer.find (class_ ='storeAddress'). get_text ()]
storeList = pd.DataFrame (
            'storeName': storeNames,
            'storeAddress': storeAddresses,
print (storeList)

    Probably because I clicked before [More] was displayed.
    Please refer to the following for the details of the error.
    stackoverflow --Scraping with selenium --click () gives an error

    Here, the place where the headless mode was once canceled and the code was executed for visual recognition
    It works normally and the page can be displayed until the end.
    I think it depends on the execution environment and the internet environment, so please adjust it yourself.

    Also, in the code in the title, the source has been acquired before executing the while statement.
    detailContainers,storeNames,storeAddressesas well asstoreListTo
    Only the first 100 items displayed by default were stored.
