在使用无服务器将lambda函数部署到LocalStack时不能使用httpApi

Question

总的来说，我对无服务器还是个新手，正在尝试在我的机器上设置LocalStack。我已经成功地将一个测试lambda函数部署到了LocalStack，但是目前面临着一个关于API Gateway的问题。

在使用下面的配置进行部署时，一切工作正常，并且我能够使用http正确访问lambda函数，并在部署结束时像往常一样打印得到的端点：

service: localtest

frameworkVersion: ">=1.74.1"

provider:
  name: aws
  runtime: nodejs12.x
  stage: local

plugins:
  - serverless-localstack

custom:
  localstack:
    stages:
      - local
    host: http://localhost  
    autostart: true 
    endpoints:
      S3: http://localhost:4566
      DynamoDB: http://localhost:4566
      CloudFormation: http://localhost:4566
      Elasticsearch: http://localhost:4566
      ES: http://localhost:4566
      SNS: http://localhost:4566
      SQS: http://localhost:4566
      Lambda: http://localhost:4566
      Kinesis: http://localhost:4566
    lambda:
      mountCode: True
    docker:
      sudo: False

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          method: get
          path: /

从serverless deploy得到的输出

Service Information
service: localtest
stage: local
region: us-east-1
stack: localtest-local
resources: 10
api keys:
  None
endpoints:
  http://localhost:4567/restapis/720w6afoyh/local/_user_request_
functions:
  hello: localtest-local-hello
layers:
  None

但是，当尝试在事件中使用httpApi实现时，

 - httpApi:
          method: get
          path: /

我从localstack得到了几个错误，该函数似乎已被部署，但没有输出路径。

来自LocalStack的错误日志：

我遇到了同样的问题。这显然只在本地堆栈的pro版本中支持，而不是免费版本。

AWS docs注意到HTTP使用-v2版本的API Gateway，根据localstack repo的说法，这只在pro版本中受支持。
