Lambda AWS Rekognition 到 DynamoDB - 错误

我正在使用本教程将 Rekognition 结果链接到 DynamoDB 表。它给了我这个错误：

{
"errorMessage": "Unable to get object metadata from S3. Check object key, region and/or access permissions.",
"errorType": "InvalidS3ObjectException",
"stackTrace": [
    "Request.extractError (/var/runtime/node_modules/aws-sdk/lib/protocol/json.js:48:27)",
    "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:105:20)",
    "Request.emit (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:77:10)",
    "Request.emit (/var/runtime/node_modules/aws-sdk/lib/request.js:683:14)",
    "Request.transition (/var/runtime/node_modules/aws-sdk/lib/request.js:22:10)",
    "AcceptorStateMachine.runTo (/var/runtime/node_modules/aws-sdk/lib/state_machine.js:14:12)",
    "/var/runtime/node_modules/aws-sdk/lib/state_machine.js:26:10",
    "Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:38:9)",
    "Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:685:12)",
    "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:115:18)"
]
}

从 GitHub 使用的代码是这个。

我确保 lambda-bucket 和表的区域名称相同。

我是这方面的初学者，所以任何帮助将不胜感激！

谢谢！

编辑：我做了一些修改，现在它给了我这个：

{
"errorMessage": "Requested resource not found",
"errorType": "ResourceNotFoundException",
"stackTrace": [
    "Request.extractError (/var/runtime/node_modules/aws-sdk/lib/protocol/json.js:48:27)",
    "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:105:20)",
    "Request.emit (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:77:10)",
    "Request.emit (/var/runtime/node_modules/aws-sdk/lib/request.js:683:14)",
    "Request.transition (/var/runtime/node_modules/aws-sdk/lib/request.js:22:10)",
    "AcceptorStateMachine.runTo (/var/runtime/node_modules/aws-sdk/lib/state_machine.js:14:12)",
    "/var/runtime/node_modules/aws-sdk/lib/state_machine.js:26:10",
    "Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:38:9)",
    "Request.<anonymous> (/var/runtime/node_modules/aws-sdk/lib/request.js:685:12)",
    "Request.callListeners (/var/runtime/node_modules/aws-sdk/lib/sequential_executor.js:115:18)"
]

}

jarmod

您所看到的事实ResourceNotFoundException表明了几个潜在的原因：

Lambda 函数找不到 DynamoDB 表：确保您修改了 config,js 以正确包含 DynamoDB 表的名称，方法是设置 config.dynamo.tableName = '<your table>'
Rekognition 无法从 S3 读取图像：确保图像文件名的格式faces.jpg为test faces.jpg（转义为test+faces.jpg）
