amazon-web-services - 为什么在此AWS Lambda部署包中找不到处理程序脚本？

Question

以下是https://docs.aws.amazon.com/lambda/latest/dg/golang-handler.html的golang示例lambda函数:

$ cat ./foo.go
package main

import (
  "fmt"
  "context"
  "github.com/aws/aws-lambda-go/lambda"
)

type MyEvent struct {
  Name string `json:"name"`
}

func HandleRequest(ctx context.Context, name MyEvent) (string, error) {
  return fmt.Sprintf("Hello %s!", name.Name ), nil
}

func main() {
  lambda.Start(HandleRequest)
}

我相信我正确地遵循了创建部署程序包的步骤:

$ GOOS=linux go build foo.go
$ zip foo.zip foo
  adding: foo (deflated 49%)
$

上面的lambda函数或部署包有什么问题？如果没有，为什么lambda create-function会失败，而无法找到处理程序脚本？

$ aws --profile jack --endpoint-url http://localhost:4574 lambda create-function --function-name foo --runtime go1.x --zip-file fileb://foo.zip --handler main --role arn:aws:iam::000000000000:role/lambda-role

An error occurred (ValidationError) when calling the CreateFunction operation: Unable to find handler script (/tmp/localstack/zipfile.07e4ae91/main) in Lambda archive. Config for local mount, docker, remote: "False", "True", "True"
$

请查看以下github问题和PR:

Support for golang lambda functions

Add golang support to lambda

可能需要一些特殊步骤才能启用/使用localstack中的go。
