Контактная форма с nodemailer

Я использую nodemailer для отправки почты, которая содержит всю информацию в форме, когда она отправлена. Здесь я успешно могу отправить почту, когда я отправляю статические данные. Но при передаче динамических данных из формы я получаю неопределенную ошибку.

Cannot read property 'name' of undefined
