Blank PDF when served from Express

Similar to #1555 but that one was closed so not sure if my comment will get any attention.
Copying my comment from there.

I am running into similar issue with my first ever nodejs service. I have following:

var headers = {} 
///Setting some custom headers for authentication

var urlObj = new URL( url );
var options = {
            path: urlObj.pathname + urlObj.query,
            headers: headers
 http.get( options, function( response ) {
            var body = '';
            response.on( 'data', function( data ) {
                body += data;
             } );

             response.on( 'end', function() {
                  res.set( 'Content-Type', 'application/pdf' );
                  res.send( new Buffer( body, 'binary' ) );
             } );
 } );

But I see a blank PDF with the correct number of pages and browser renders it as a PDF but all pages are empty.
Accessing the url directly shows the right pdf so the pdf is fine.
Any input will be really appreciated.

  1. Thanks. Yes request module really simplified the code a lot to basically one liner.

    request.get( { url: url, headers: headers } ).pipe( res );
