How does express pull the error pug template when passwords don't match. I don't see a route defined for this template.

I have checked the project code and as it says in the title, I just don't understand how the template error.pug gets activated when for instance the user misspells his/her password.

when the password is incorrect, it creates an error and passes it with next(err), this "next(err)" is then passed along until it reaches the error handler found at the bottom of app.js. there the error pug is rendered with the designated error message defined in the original route where the error was created. so there is no error route that renders the error pug. rather, the route is passed to the error handler in app.js where the error.pug is rendered.
