BoxOfficeMojo отказывается от соединений с Selenium. Прекрасно сочетается с красивым супом, так что это не настоящая связь

Кто-нибудь знает, что происходит? Я собираюсь выбросить свой компьютер в окно. Красивый суп отлично работает с той же страницей, поэтому я знаю, что это не связь. И я пробовал помещать WebDriverWait и time.sleep(10) между каждой строкой - после задержки возникает такая же ошибка. 

from bs4 import BeautifulSoup
import requests
import time, os
import pandas as pd
import re

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait

chromedriver = "/usr/bin/chromedriver" # path to the chromedriver executable
os.environ["webdriver.chrome.driver"] = chromedriver

i = 2
driver = webdriver.Chrome(chromedriver)
driver.get('https://www.boxofficemojo.com/year/2020/?ref_=bo_yl_table_1')
wait = WebDriverWait(driver, 10)
wait
while i < 269:
    wait
    driver.find_element_by_xpath('//*[@id="table"]/div/table[2]/tbody/tr[{}]/td[2]/a'.format(i)).click()
    wait
    get_movie_dict(driver.current_url)
    wait
    i += 1
    wait
    driver.back()

Я получаю следующие ошибки:

Я выяснил, в чем проблема. После удаления этого блока из get_movie_dict функция работала правильно: 

#Request HTML and parse
wait = WebDriverWait(driver, 10)
wait
response = requests.get(url)
wait
page = response.text
soup = BeautifulSoup(page,"lxml")

get_movie_dict - вспомогательная функция. Строка с response = requests.get(url) пыталась отправить другой, несвязанный запрос GET внутри вспомогательной функции, что было ненужным, потому что один уже был отправлен за ее пределами - это и было причиной проблемы.

Это пример того, почему важно понимать, что делает каждая строка кода, прежде чем копировать и вставлять ее в свой собственный код.

link, который вы извлекаете со страницы, является «абсолютным» (он включает схему и имя хоста), когда вы добавляете его к base_url, вы получаете строку, которая выглядит как https://www.boxofficemojo.comhttps://www.boxofficemojo.com/release/rl1182631425/?ref_=bo_yld_table_1

Вы должны использовать urljoin, чтобы объединить базовый URL-адрес с извлеченным URL-адресом, поскольку он будет обрабатывать как относительные, так и абсолютные URL-адреса. 

from urllib.parse import urljoin
url = urljoin(base_url, link)
