Whenever I try to run this code

```
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
browser = webdriver.Chrome()
browser.get("https://kahoot.it/") 
time.sleep(10)
code = browser.find_element_by_id("inputSession")
code.send_keys("273976")
login_attempt = browser.find_element_by_xpath("//*[@type='submit']")
login_attempt.submit()

```

I get the error

```

```

if there is any help it would be greatly appreciated since it's pretty confusing, I think it's something to do with the modules but I've tried uninstalling and reinstalling twice.

Thanks!
