Question

我在使用弹性beanstalk托管的匿名自动售货机时遇到了麻烦。情况是我正在使用AWS为iOS提供的代码，但是为密码生成的密钥生成uid /密钥获得了500秒。豆茎日志似乎相当稀疏，但显示了500，所以他们至少在说话。

这个空指针异常似乎是唯一的详细错误，虽然我不确定它指向的是什么问题。

Answer 1

我知道这是一个有点老问题。但是我在环境中运行TVM时遇到了同样的问题（Amazon beanstalk微实例）一旦我重新启动beanstalk实例，这个问题就解决了。但是为了确保您没有再次收到此错误，您必须确保用于访问TVM的IAM用户的用户策略被复制到已部署的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
