Uncaught NetworkingError: Cannot read property 'replace' of undefined Error

Question

我在尝试运行以下代码时遇到以下错误。我的目标是删除 User 和 Item 表中的所有项目。 User和Item对应Dynamoose个机型。

for 循环运行ning 正确。但是 scan().exec 回调函数根本就不是运行，它会抛出以下错误。

真正奇怪的是在CircleCI 上并没有出现这个问题。它只发生在我的本地计算机上。我尝试删除 node_modules 和运行ning npm install 但没有成功。如果我删除下面的代码，它也可以正常工作。

有什么想法吗？或者甚至从哪里开始调试这个？

代码：

var dbarray = [User, Item];
for (var i = 0; i < dbarray.length; i++) {
    dbarray[i].scan().exec(function(err, items) {
        if (err) {
            throw err;
        }
        items.forEach(function(item, key) {
            item.delete();
        });
    });
}

错误：

问题出在 Zombie.js。特别是Browser.localhost('localhost', port);。在每个访问命令之前删除该行并传入 http://localhost:3000 解决了问题。

不确定为什么错误会提到 AWS 和类似的东西。
