Custom::LambdaTrigger 资源在使用 Cloud Formation 时卡在 CREATE_IN_PROGRESS

Question

我正在尝试使用 AWS Cloud Formation 创建堆栈。我有一个导致问题的 Custom::LambdaTrigger 资源。

资源卡在 CREATE_IN_PROGRESS 很长时间。参考下图：

按照对应的成云代码：

 "ApiDeployerTrigger": {
            "Type": "Custom::LambdaTrigger",
            "Properties": {
                "ServiceToken": {
                    "Fn::GetAtt": [
                        "ApiDeployer",
                        "Arn"
                    ]
                },
                "RestApiId": {
                    "Ref": "ApiGateway"
                },
                "StageName": "v1",
                "SeqNo": {
                    "Ref": "PackageVersion"
                }
            },
            "DependsOn": [
                "ApiGateway"
            ]
        }

然后，它创建失败并发生回滚。

然后回滚也失败了

更新： 我查看了 CloudWatch 日志。我收到以下错误：

以下是创建 lambda 函数的代码：

        }

任何线索，有什么问题？

似乎是 lamda 运行时 nodejs10.x 的问题。

找不到 cfn-response 模块。

将var response = require('cfn-response') 更改为var response = require('./cfn-response') 解决了这个问题。
