用AWS、lambda和middy修复未知的http事件格式？

Question

这是个测试灯。应在何处指定格式？middy现在是否需要在某个地方指定event.requestContext.http.method？

import 'source-map-support/register';

import type { ValidatedEventAPIGatewayProxyEvent } from '@libs/apiGateway';
import { formatJSONResponse } from '@libs/apiGateway';
import { middyfy } from '@libs/lambda';

import schema from './schema';

const hello: ValidatedEventAPIGatewayProxyEvent<typeof schema> = async (event) => {
  return formatJSONResponse({
    headers: {
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Credentials': true,
    },
    message: `Hello ${event.body.name}, welcome to the exciting Serverless world!`,
    event,
  });
}

export const main = middyfy(hello);

环境是

"@middy/core": "^3.1.0",
"@middy/http-cors": "^3.1.0",

使用无服务器:框架核心: 3.21.0 (本地) 3.21.0 (全局)

执行是通过

无服务器调用本地--函数hello --路径src/function/hello/mock.json

"errorMessage": "[http-cors] Unknown http event format",
"errorType": "Error",
"stackTrace": [
    "Error: [http-cors] Unknown http event format",
    "    at httpCorsMiddlewareAfter (/Users/jrobens/NetBeansProjects/azuron/winpay/winpay-admin-api/node_modules/@middy/http-cors/index.cjs:82:19)",

@middy/ HTTP -cors支持REST (v1)和HTTP (v2) AWS事件。您的测试事件并不完全符合HTTP (v2) AWS事件结构。让它包含event.requestContext.http.method将解决这个问题。AWS文档中的示例：https://docs.aws.amazon.com/lambda/latest/dg/services-apigateway.html。
