Getting an error with the request module

I'm doing a query to the mtgox server. Here is the API https://en.bitcoin.it/wiki/MtGox/API/HTTP/v1. My code successfully hits the server but after a a few times this error pops up:

events.js:115
      listeners[i].apply(this, args);
                   ^
TypeError: Cannot call method 'apply' of undefined
    at EncryptedStream.EventEmitter.emit (events.js:115:20)
    at SecurePair.destroy (tls.js:896:22)
    at process.startup.processNextTick.process._tickCallback (node.js:244:9)

I'm pretty sure this isn't from the API call limits.

//the following function returns general ticker information in USD. This includes high, low, and volume...

exports.market_data = function(req, res, next){
  console.log("test");
  options = {
    uri: 'http://mtgox.com/api/1/BTCUSD/ticker',
    headers: {
      'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/555.55 (KHTML, like Gecko) Chrome/55.5.5555.55 Safari/555.55'
    }
  };
  try {
    request(options, function (err, response, body) {
      // console.log(body);
      APIResponder.respond(res, response);
    });
  } catch(err) {
      console.log(err);
      console.log("Gangnam style");
    throw err;
  }
};

Sorry for the delay, Internet died. Here is the code that queries MTGox. Hope this helps.
