Again error is coming out, I'm using this code to send mail, okay?

´´´
function afterRender(req, res, done) {
var mailer = require('nodemailer');

var smtpTransport = mailer.createTransport('smtps://user%40gmail.com:pass@smtp.gmail.com');

var mail = {
    from: "Jan Blaha <malca.kike.9@gmail.com>",
    to: "marlon.50294@gmail.com",
    subject: "Sending email from node.js",
    text: "See the attached report",
    html: "<b>See the attached report</b>",
    attachments: [
    {  
        filename: 'Report.pdf',
        content: new Buffer(res.content)
    }],
}

smtpTransport.sendMail(mail, function(error, response){
    smtpTransport.close();
    if(error){
        return done(error);
    }

    return done();
});

}
´´´

the same thing keeps coming

is configured with this code

{
   "extensions": {
     "scripts": {
       "allowedModules": ["request"]
     }
   }
}

I'm trying to send an email, and install the nodemailer, but I get this error when I run, help !.
