Invalid signature error only from module exports.

[bugs181]

To further explain the issue, if I call yelp.search() from within the module, everything works out and I receive data. However if I call that very same function using module.exports function I receive an invalid signature error.

Error:

{"error": {"text": "Signature was invalid", "id": "INVALID_SIGNATURE", "description": "Invalid signature. Expected signature base string: GET\u0026http%3A%2F%2Fapi.yelp.com%2Fv2%2Fsearch\u0026location%3DReno%252C%2520NV%26oauth_consumer_key%3D_removed_%26oauth_nonce%3D_removed_%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1389681156%26oauth_token%3D_removed_%26oauth_version%3D1.0%26term%3D"}}

Here is my code.

var yelp = require("yelp").createClient({
  consumer_key: "my_consumer_key", 
  consumer_secret: "my_consumer_secret",
  token: "my_token",
  token_secret: "my_token_secret"
});

module.exports = {
  search: function(req, res, callbacker) {

    // Does not work and throws Invalid Signature error
    yelp.search({term: "", location: "Reno, NV"}, function(error, data) {
      if (data)  console.log(data);
    });

  }
}

// Works as expected here.
yelp.search({term: "", location: "Reno, NV"}, function(error, data) {
    if (data)  console.log(data);
});

What could the issue be?

Also, to note. If I just wrap yelp.search() in another function (outside module.exports) and call that from module.exports->search(), it still throws the error.

Found the issue. This is why you shouldn't mess with the prototypes boys and girls. ;)

Apparently oath is very strict about the typeof something.

Object.prototype.typeof = function(object) {
  if (!object) { object = this }

  if (typeof(object) === "object" && 'splice' in object && 'join' in object) {
    return 'array';
  }

  return typeof(object);
}

Actually, this is an oauth issue. Any time the object.prototype is modified, oauth throws that error.

Thanks for pointing this out.
