“invalid argument: invalid 'expiry'”

I'm trying to add cookies to a browser, but getting the following error: How to fix “invalid argument: invalid 'expiry'” in Selenium when adding cookies to a chromedriver?

pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))

driver.get ( URL )
sleep ( 2 )

cookies = pickle.load(open("cookies.pkl", "rb")) 
for cookie in cookies: 
    driver.add_cookie(cookie)
    sleep(2)

driver.get ( URL )

print(driver.get_cookies())
pickle.dump( driver.get_cookies() , open("cookies.pkl","wb"))

Error msg

first of all follow link from comment to change pickle to dict

expiry should be now int not float.

for cookie in cookies:
    if isinstance(cookie.get('expiry'), float):
        cookie['expiry'] = int(cookie['expiry'])
    driver.add_cookie(cookie)
