我对 AWS 和 Greengrass v2 还很陌生，一步一步我似乎掌握了窍门。但现在我被困住了，我想在这里问这个问题：
- 我使用该
--provision true选项安装了一个正常运行的 Greengrass Core 设备，因此安装程序会自动生成角色和别名 - 我能够向IoTCore发送消息并返回
- 我能够根据特定主题触发Lambda函数
- 我正在运行以下 AWS 提供的组件：
- 核
- 影子管理器
- 流管理器
- 代币兑换服务
- 客户端设备.Auth
- clientdevices.mqtt.Bridge
- 客户端设备.mqtt.Moquette
- 我向 IAM 角色添加了能够将数据推送到IoTAnalytics的策略

"arn:aws:iotanalytics:region:account-id:channel/channel_2_name"
]
}
]
}
我创建了一个自定义组件
该组件能够：
- 连接到 StreamManager
- 在 StreamManager 上创建流
- 每 10 秒将消息附加到创建的流中
这些是组件的日志文件，一切看起来都很好：

StreamManager 更新
但是 StreamManager 在尝试将数据上传到IoTAnalytics时似乎会出错。这些是aws.greengrass.StreamManager.log
来自我可以阅读的错误日志 StreamManager 似乎无法从 Greengrass 获取 AWS 凭证

有关完整信息，这些是此要点中 Stream Manager 的完整调试日志。错误在第 167 行
我希望有人可以帮助我，这样我就可以将我的测量数据发送给 IoTAnalytics。
谢谢！问候
