How to fix “invalid argument: invalid 'expiry'” in Selenium when adding cookies to a chromedriver?

Question

I\'m trying to add cookies to a browser, but getting the following error:

Message: invalid argument: invalid \'expiry\' (Session info: chrome=75.0.3770.90)

Answer 1

In my case, the previous answer did not work. I had to remove the expire key from the object.

 for cookie in pickle.load(open(PATH, "rb")):
     if 'expiry' in cookie:
         del cookie['expiry']

     self.driver.add_cookie(cookie)

This happens if you previously pickled the cookies directly as they're returned from the driver, like so:

pickle.dump(browser.get_cookies(), open(PATH, "wb"))
