Write downloaded image to pdfkit using nodejs

I am trying to write an image scraped&downloaded from a website using request to pdfkit.

var request = require('request'),
    PDFDocument = require('pdfkit'),
        doc = new PDFDocument,
        fs = require('fs');

var wstream = fs.createWriteStream('images/0.jpeg')
var r = request(IMAGEURL).pipe(wstream);
r.on('close', function() {
        doc.image('images/0.jpeg');
    });
doc.end();

Problem is, no image is added to the pdf:-(

This is the error message I get:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: stream.push() after EOF

Any idea how to solve this?
