How to clear req.session.array?

I am trying to display errorMessages to the user once after they fail registration. If the registration page is visited again the errorMessages array will not be displayed. For some reason req.session.errorMessages is being displayed on every request to the registration page. 

module.exports.registration = function(req,res){

    if(Array.isArray(req.session.errorMessages) && req.session.errorMessages.length > 0)
        res.locals.errorMessages = req.session.errorMessages;
    else
        res.locals.errorMessages = [];

    res.render('registration',{

    });

    //This line does not seem to reset the array after the response has been rendered
    req.session.errorMessages = [];

};

Move it above the render call. It seems that you can't change req or res anymore after returning data to the user.
