makeWebRequest Not working, any ideas?

I'm trying to get web requests going starting the the JsonTransaction example and i keep getting an error complaining about the callback method not being valid.  I'm api level 3.3.0 any thought on why the simulator doesnt like this callback method?

import Toybox.System;
import Toybox.Communications;
import Toybox.Lang;

class JsonTransaction {
    // set up the response callback function
    function onReceive(responseCode as Number, data as Dictionary) as Void {
        if (responseCode == 200) {
            System.println("Request Successful");                   // print success
        } else {
            System.println("Response: " + responseCode);            // print response code
        }
    }

    function makeRequest() as Void {
        var url = "https://www.garmin.com";                         // set the url

        var params = {                                              // set the parameters
            "definedParams" => "123456789abcdefg"
        };

        var options = {                                             // set the options
            :method => Communications.HTTP_REQUEST_METHOD_GET,      // set HTTP method
            :headers => {                                           // set headers
            "Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED},
            // set response type
            :responseType => Communications.HTTP_RESPONSE_CONTENT_TYPE_URL_ENCODED
        };

        var responseCallback = method(:onReceive);                  // set responseCallback to
        // onReceive() method
        // Make the Communications.makeWebRequest() call
        Communications.makeWebRequest(url, params, options, responseCallback);
    }
}

error
