amazon-web-services - 由于缺少参数，使用 CDK 部署 Lambda 函数失败

问题描述

new Function(this, "TestFunction", {
    handler: "TestFunction.handler",
    code: Code.asset(path.join(__dirname, "lambdas/")),
    runtime: Runtime.NodeJS810
});

当我尝试将其部署到 CodeDeploy 时，我得到：

Parameters: [TestFunctionCodeS3Bucket, TestFunctionCodeS3VersionKey] must have values (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError;

当我检查生成的 CloudFormation 时，我可以看到参数：

TestFunctionCodeS3Bucket:
    Type: String
    Description: S3 bucket for asset "AppStack/TestFunction/Code"
TestFunctionCodeS3VersionKey:
    Type: String
    Description: S3 key for asset version "AppStack/TestFunction/Code"

我的理解是Code.asset应该自己引导这个过程。我在这里缺少一个步骤吗？

查看文档（https://docs.aws.amazon.com/cdk/latest/guide/serverless_example.html），它指出您应该创建一个Amazon S3 bucket that contains the Lambda function code.但是，在示例中我没有看到正在完成明确地。所以我只是假设它是隐式完成的。
