Hi,

I am receiving a pdf file from the server on the internet. This is in binary format and as soon as I try adding it in a callback, the file gets corrupted/damaged. Whereas if I simply return the file without a cb, it gets downloaded.

_var options = {
url: config.baseURL + config.getDocument.url + docId,
encoding: null,
method: 'GET',
qs: {'a': true, 'alf_ticket': ticket}
};

// send out request
request(options, function(error, response, body) {onGetDocumentResponse(error, response, body, callback);});
}
_

In my remote method when I do the following

_ params.res.setHeader('Content-Type', 'application/pdf');
params.res.setHeader('Content-Disposition', 'attachment; filename=' + params.docid + '.pdf');

  return params.res.end(result.body);_

It downloads the file perfectly, but as soon I introduce callback

_cb(null,result.body);
_
The pdf received is damaged (size is 195 bytes vs 4kb of original file)

I've read on multiple threads of having issues in downloading pdfs in node. Is there any solution that you could recommend which would allow us to use a callback instead of a return statement (since that would intercept all middleware)
