我正在我的应用程序中实现AWS DynamoDB。由于某些原因，当我运行应用程序时，由于服务配置为零，所以出现“ NSInternalInconsistencyExceptionException”错误。指示我在“使用此方法”之前配置Info.plist或设置“ defaultServiceConfiguration”。这是什么意思，我应该采取什么措施才能完成此配置？
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The service configuration is `nil`. You need to configure `Info.plist` or set `defaultServiceConfiguration` before using this method.'
