POST with HTTPBuilder -> NullPointerException?

Question

I\'m trying to make a simple HTTP POST request, and I have no idea why the following is failing. I tried following the examples here, and I don\'t see where I\'m going wrong

If you need to execute a POST with contentType JSON and pass a complex json data, try to convert your body manually:

def attributes = [a:[b:[c:[]]], d:[]] //Complex structure
def http = new HTTPBuilder("your-url")
http.auth.basic('user', 'pass') // Optional
http.request (POST, ContentType.JSON) { req ->
  uri.path = path
  body = (attributes as JSON).toString()
  response.success = { resp, json -> }
  response.failure = { resp, json -> }
}
