amazon-web-services - 云信息 "update your Lambda function code so that CloudFormation can attach the updated version"

Question

我正在从此 blog post 部署 CloudFormation 模板。我必须将 Lambda 函数从 python 3.6 更新到 3.9 才能使其正常工作。但是现在我收到以下错误消息:

> CloudFormation did not receive a response from your Custom Resource.
> Please check your logs for requestId
> [029f4ea5-cd25-4593-b1ee-d805dd30463f]. 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.

下面是相关的 lambda 代码 - 更新 Lambda 函数“以便 CloudFormation 可以附加更新的版本”意味着什么？

    import util.cfnresponse
    import boto3
    import uuid
    
    client = boto3.client('s3')
    
    cfnresponse = util.cfnresponse
    
    def lambda_handler(event, context):
        response_data = {}
        try:
            if event["RequestType"] == "Create":
                bucket_name = uuid.uuid4().hex+'-connect'
                # response = client.create_bucket(
                #     Bucket=bucket_name,
                # )
                response_data["BucketName"] = bucket_name
                cfnresponse.send(event, context, cfnresponse.SUCCESS, response_data)
    
            cfnresponse.send(event, context, cfnresponse.SUCCESS, response_data)
        except Exception as e:
            print(e)
            cfnresponse.send(event, context, cfnresponse.FAILED, response_data)

据我所知，响应格式遵循当前版本的 response module API ？

cfnrespone 库已更改并更新。旧版本的库使用请求库。这个 CF 已经有 4 年多了，所以它可能因此而无法工作。您可以在此处阅读自述文件最后几行的更新: https://github.com/gene1wood/cfnresponse
