Got this issue

I used the quickstart installation in aws server but i still get this issue.

Traceback (most recent call last):
File "quickstart.py", line 24, in

処理は24行目の quickstart.py から始まり、Selenium の Firefox WebDriver を経由して114行目の instapy/browser.py に到達します。まず AWS サーバー上の quickstart インストールを使って SessionNotCreatedException を再現し、報告された capability の不一致を調査してください。quickstart がこの例外なしでブラウザーセッションを起動できれば完了です。
