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

selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities

The report starts in quickstart.py at line 24 and reaches instapy/browser.py at line 114 through Selenium's Firefox WebDriver. First reproduce the SessionNotCreatedException using the quickstart installation on the AWS server and inspect the reported capability mismatch. Done means the quickstart launches a browser session without this exception.
