aws-lambda - 为 lambda 创建自定义资源触发器时出错

Question

我通过 ts 文件创建了一个具有以下规范的 lambda:

        description: 'Lambda request handler to automate the DDL commands',
        name: LAMBDA_NAME,
        timeout: Duration.minutes(10),
        memorySize: 512,
        componentName: 'DdlLambda',
        runtime: Runtime.JAVA_11,
        handler: 'handler.ddllambda',
        packageName: 'DDLManagementLambda-1.0',
        deadLetterQueueEnabled: false,
        tracing: Tracing.ACTIVE,
        profiling: false,
        logRetention: RetentionDays.FOUR_MONTHS

创建自定义资源

import {CustomResource} from "monocdk";

const customResource = new CustomResource(this, 'CustomResource', {
  serviceToken: ddllambda.functionArn,
  properties: {
      version: "version_0"
  }

但我收到错误

CloudFormation did not receive a response from your Custom Resource. 
Please check your logs for requestId [c634da01-9c4d-4f8e-a2fc-a28724aa8206]. 
If you are using the Python cfn-response module, you may need to update your 
Lambda function code so that CloudFormation can attach the updated version.

我无法找到给定 requestId 的日志。我在这里缺少什么？

Answer 1

您应该使用cfn-response.send在您的自定义资源中通知 CloudFormation。

在控制台中查找日志:

对于日志，您可以从 lambda 页面中的控制台访问它们，点击监控，然后在 CloudWatch 中查看日志:

进入CloudWatch后，点击搜索全部:

然后在搜索框中将您的请求 ID 粘贴到双引号中:

使用 aws-cli 查找日志:请参阅 this answer
