Thanks for the report @mafsan786git . What steps do I need to take to be able to run that code above in order to reproduce the error?

Because you have passReqToCallback:true at https://github.com/mafsan786git/LoginSystem/blob/8c6b04818760ce55014925b1d27655b0e50961b7/config/passport.js#L12 the first agument to your callback is the request, not the email. Just remove that configuration.
