Access body for failed easyRequest call

The easyRequest dependency.js does not return the body of the request if an error response code is returned from the request. Is there any way to get at the body?

/**

easyRequest

- Provides a layer of abstraction to easily query HTTP endpoints.
- It does all the error handling (bad response, authentication failed, bad json response, etc).
*/

module.exports = function (jobWorker, io, globalConfig){
  var request = require('request');

  function query_request (options, callback) {
    request(options, function(err, response, body){
      if (err || !response || response.statusCode != 200) {
        var error_msg = (err || (response ? ("bad statusCode: " + response.statusCode) : "bad response")) + " from " + options.url;
        callback(error_msg);
      }
      else {
        callback(null, body);
      }
    });
  }
