node.js html-pdf conversion issue, file is coming back corrupt

Question

I am trying to create an application that will take an html file that is populated using a jquery get request. I am making an http get request to get the html, passing the string to the pdf.create function and using the generated buffer to send a pdf file via email. This seems to process and send the file off as an email attachment, however, when I try to open the file I am receiving an error saying the file is corrupt.

code that convert html document to pdf:
                var options = {
                  host: 'localhost',
                  path: '/salesorder/' + orderid,
                  port: '3000'
                };

                http.request(options, function(response){
                  let buffer = '';
                  response.on('data', function (chunk) {
                      buffer += chunk;
                  });

                  response.on('end', function () {
                    pdf.create(buffer, {
                        directory: "tmp"
                    }).toBuffer(function(err, newbuffer){
                        if (err){
                            reject(err);
                        }

                        if (Buffer.isBuffer(newbuffer)){
                            resolve(newbuffer);
                        } else {
                            reject(new Error('The pdf file could not be generated at this time.  Please try again later.'));
                        }
                    });
                  });
                })
                .end();


code that sends the email:
    var transporter = nodemailer.createTransport({
        service: 'gmail',
        host: this.hostname,
        auth: {
            user: this.smtpusername,
            pass: this.smtppassword
        }
    });

    var mailOptions = {
        from: fromaddress, // sender address
        to: toaddresslist, // list of receivers
        subject: subject, // Subject line
        text: text
    };

    if (attachments){
        mailOptions.attachments = [
            {   // binary buffer as an attachment
                filename: 'invoice.pdf',
                content: new Buffer(attachments.toString(), 'base64'),
                contentType: 'application/pdf'
            }
        ];
    }

I am using html-pdf node.js package to perform the conversion. What am I missing here? I am taking the html I get from the http.request method and I can see the code generated if I print it out using console.log it out. Now I notice that I am not seeing the text fields and labels populating, so it does not seem like the jquery is processing.

I'm not experienced with nodemailer, but it seems to me that you are missing encoding: 'base64' on your attachment. See the docs here.
