Jake and Bluebird don't play well together?

I'm not sure whether it's an issue with Jake or Bluebird but when I'm doing the following thing.

//import * as FS from "fs";
import * as Promises from "bluebird";

let fs = Promise.promisifyAll(require("fs"));

task("default", function() {
});

I'm getting the following error.

TypeError: undefined is not a function

I tried to change it to the following thing and still I get the same error.

let fs = Promise.promisifyAll(new Object());

P.S. I'm using TypeScript to compile it but I don't think it has anything to do with it because the compiler compiles it just fine.

never mind it was a typo!
