我在弹性豆茎上托管的匿名自动售货机遇到问题。情况是我正在使用 AWS 为 iOS 提供的代码，但是为 KeyWrapper 生成的加密生成的 uid / 密钥获得了 500 秒的回报。豆茎原木似乎很稀疏，但显示了 500 多条，所以它们至少在说话。

这个空指针异常似乎是唯一的详细错误，尽管我不确定它指向什么问题。

我知道这是一个有点老的问题。但是我在环境中运行TVM时也遇到了同样的问题（亚马逊beantalk微实例）一旦我重新启动beantalk实例，这个问题就得到了解决。但是为了确保您不会再次收到此错误，您必须确保将用于访问 TVM 的 IAM 用户的用户策略复制到部署的 TVM 中的“TokenVendingMachinePolicy.json”文件中应用。有关详细信息，请参阅http://aws.amazon.com/code/8872061742402990
