    I ran into this issue when I changed the WebApi I was calling to return a Task instead of the previous IEnumerable. Check the response isn't wrapped in an object. I had to change my extractData method to:

    private extractData(res: Response) {
   let body = res.json();
   return body.result || body || { };
}
