pinterestというサイトにrequestsでpostログインし、その後ログインセッションseleniumに渡し操作したいのですが上手く行きません。  
以下のコードを実行して見るのですが、エラーが出ず固まって動かなくなってしまいます。  
詳しい方見て頂けないでしょうか？よろしくお願いします。

```

    import requests
    from selenium import webdriver
    from bs4 import BeautifulSoup
    
    #サーバの認識するブラウザ情報
    ua = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36'
    headers = {'User-Agent': ua}
    
    #＃seleniumを使用する準備
    options = webdriver.ChromeOptions()
    options.add_argument('--headless')
    driver = webdriver.Chrome('selenium/chromedriver', options=options)
    
    
    login_url = 'https://accounts.pinterest.com/v3/login/handshake/'
    userdata = {'username_or_email':'xxxxxxxxxxx', 'password':'yyyyyyyyyyyyy'}
    
    authorization_url = 'https://api.pinterest.com/oauth/'
    
    payload = '?response_type=code&client_id=xxxxxxxxxxxx&redirect_uri=https://x.x.x.x:9000/callbackpage&scope=read_public,write_public,read_relationships,write_relationships'
    
    
    
    def get_code():
        with requests.Session() as s:
            p = s.post(login_url, params=userdata)
            driver.delete_all_cookies()
            driver.get('https://www.pinterest.jp/')
            [s.cookies.set(c['name'], c['value']) for c in driver.get_cookies()]
    
            c_dict = s.cookies.get_dict()
            cookie = [{'name': name, 'value': value} for name, value in c_dict.items()]
            [driver.add_cookie(c) for c in cookie]
            print('ok')
    
            #ログインが成功してるならここで承認が必要なページになる。
            authorization_url_payload = authorization_url + payload
            driver.get(authorization_url_payload)
            soup = BeautifulSoup(driver.page_source, 'lxml')
            print(soup.body)
    
    get_code()
    
```

途中で止めた際に吐き出されたエラー
