I am receiving the error:

When parsing Twitter API JSON from the Search API.

The code I am using the parse this JSON is:

MongoClient.connect("mongodb://localhost:27017/db", function(err, db) {

 if(err) { return console.dir(err); }
  var collection = db.collection("tweets");

    while(run < 200){

        oa.get("http://search.twitter.com/search.json?q=morning&rpp=100&include_entities=true&result_type=mixed", access_token, access_token_secret, function(error, data) {
            var theTweets = JSON.parse(sys.inspect(data));

           collection.insert(theTweets, {w:1}, function(err, result) {});
           console.log(run);
        });
    run = run + 1;
    }

});

What could cause this?

Why are you sys.inspect()ing data? I would expect data is either JSON, so you should just JSON.parse(data), or it's already a native JS object, so you don't need to parse it at all. – Matt Ball 9 hours ago

The problem is on the sys.inspect() call as already stated by the other answers and comments.

As stated in the nodejs documentation (http://nodejs.org/api/util.html#util_util_inspect_object_options):

Return a string representation of object, which is useful for debugging.

By the way, it seems they changed the sys module name to util.

You can easily make a small test by running the following code on an older node version. It should throw your error:

var sys = require('sys');
var data = '{"test":1, "test2":2}';
sys.puts(JSON.parse(sys.inspect(data)));

And then remove the sys.inspect call. It should correctly parse the object:

var sys = require('sys');
var data = '{"test":1, "test2":2}';
sys.puts(JSON.parse(data));

Why are you using sys.inspect?

If data is a JSON string, then use JSON.parse(data); and if it's an object already, well you don't have to use JSON.parse at all...

Probably, the output of sys.inspect is not JSON it adds the quote '.
