堤坝，断路器模式，在执行时引发异常

Question

我是Node.js的新手，遇到了用作断路器的堤坝，当我执行以下代码时，会发生异常

   'use   strict';

    var  Levee = require('levee');
    var  Wreck = require('wreck');

    var options, circuit;

    options = {
        maxFailures: 5,
        timeout: 60000,
        resetTimeout: 30000
    };

    circuit = Levee.createBreaker(Wreck.get,       options);

    circuit.run('https://www.google.com',        function (err, req, payload)
     {
        // If the service fails or timeouts occur 5 consecutive times,
        // the breaker opens, fast failing subsequent requests.
        console.log(err || payload);
    });

例外情况如下
