Nodemailer在浏览器中显示电子邮件，而不是发送电子邮件

Question

我正在尝试使用email-templates软件包，但是遇到了问题。一切正常，直到我将路径从静态文件更改为url。从那时起，每当我尝试发送电子邮件时，它只会在浏览器中显示临时文件，而不是实际通过电子邮件发送任何内容。我尝试将其改回，但问题仍然存在。由于这是关于附件的，因此我假设这是一个nodemailer问题，而不是电子邮件模板问题。 这是我的代码：

const Email = require("email-templates");
email = new Email({
    message: {
        from: "pribehytest@seznam.cz"
    },
    // uncomment below to send emails in development/test env:
  // send: true
  transport: {
    host: "smtp.seznam.cz",
       port: 465,
    secure: true,
    auth: {
        user: "mail",
        pass: "password"
    }
  }
})

// this is in a different file
pdf.create(compiledPugInvoice({
    // some locals
}), {format: "Letter"}).toFile("emails/newOrder/invoices/invoice" + orderID + ".pdf", (err, result) => {
    if(err) next(err);
    else{

        cloudinary.uploader.upload("emails/newOrder/invoices/invoice" + orderID + ".pdf", (cloudinaryResult) => {
            console.log(cloudinaryResult);

            // send an email to the client
            email
                .send({
                    template: "newOrder",
                        message: {
                            to: req.body.email,
                                attachments: [
                                    {
                                        filename: "faktura.pdf",
                                        path: cloudinaryResult.secure_url
                                    }
                                ]
                            },
                        locals: {
                            // some locals
                            }
                        })
                            .then(() => {
                                fs.unlink("emails/newOrder/invoices/invoice" + orderID + ".pdf", (err) => {
                                    if(err) next(err);
                            }))
                            .catch(console.error);

                        });
