Hi Ravi, thanks for raising this question.
It is mandatory to have an email address as it is required by many tasks inside moodle.
So, unfortunately without email address set it is not possible to log in using their Facebook account.
The error you have reported is a different thing, related to events where we don't have the username to set on user_login_failed event class.
Thanks.
