未捕获的 NetworkingError：无法读取未定义错误的属性“替换”答案

【问题标题】：Uncaught NetworkingError: Cannot read property 'replace' of undefined Error未捕获的 NetworkingError：无法读取未定义错误的属性“替换”
【发布时间】：2018-03-24 19:42:57
【问题描述】：

尝试运行以下代码时出现以下错误。我的目标是删除 User 和 Item 表中的所有项目。用户和项目对应Dynamoose模型。

for 循环运行正常。但是 scan().exec 回调函数根本没有运行，它抛出了以下错误。

真正奇怪的是在 CircleCI 上这个问题不会发生。它只发生在我的本地计算机上。我试过删除 node_modules 并运行 npm install ，但没有成功。如果我删除下面的代码也可以正常工作。

有什么想法吗？甚至从哪里开始调试？

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：

【问题讨论】：

标签： javascript node.js zombie.js

【解决方案1】：

问题出在Zombie.js。特别是Browser.localhost('localhost', port);。删除该行并在每个访问命令之前传递http://localhost:3000 即可解决问题。

不知道为什么错误提到了 AWS 和类似的东西。
