node.js - SendPulse + NodeJS: Attachment Issues -

i've written following nodejs app send email attachment.

the problem is, email attachment

2. the file cannot opened word (it says corrupt).

by way, i've tried "attachments_binary" trying use "base64" encoding filereadsync no avail.

var fs = require('fs');

var sendpulse = require('sendpulse');

sendpulse.init("{secret}", "{key}", "lite");  var fbuff = fs.readfilesync('c://nodejs//projects//devstat//test.docx', 'base64');      var mailitem = {      html: '<h1>test email</h1>',     text: '',     subject: '[test email]',     from: { name: 'john doe', email: '(name)@gmail.com' },     to: [ { name: 'jane doe', email: '(name)@domain.com' } ],     attachments: [ { 'test.docx': fbuff } ] };  var answergetter = function(data) { console.log(data); }  sendpulse.smtpsendmail(answergetter, mailitem);
