如何在AWS Lambda中运行带experimental-edge runtime的Next.js并生成OG图片

我在AWS Lambda中部署带OG图片生成逻辑（依赖@vercel/og的ImageResponse）的Next.js 13.0.6项目，本地开发和生产构建后直接运行都正常，但调用Lambda处理程序时，依赖runtime: 'experimental-edge'的接口始终返回statusCode: 500错误，问题应该出在Edge Runtime的配置上。

我的部署流程与代码 #

1. 执行next build构建项目，next.config.js中配置了output: 'standalone'，生成.next/standalone目录
2. 在standalone目录下编写handler.js作为Lambda入口：

const { parse } = require('url');
const NextServer = require('next/dist/server/next-server').default
const serverless = require('serverless-http');
const path = require('path');
process.env.NODE_ENV = 'production'
process.chdir(__dirname)

const currentPort = parseInt(process.env.PORT, 10) || 3000

const nextServer = new NextServer({
  hostname: 'localhost',
  port: currentPort,
  dir: path.join(__dirname),
  dev: false,
  customServer: false,
  conf: {...} // 从同目录下的server.js中复制配置内容
});


const requestHandler = nextServer.getRequestHandler();

// 将Lambda事件转换为Next服务器可处理的HTTP请求
const handler = serverless(async (req, res) => {
  try {
    await requestHandler(req, res);
  }catch(err){
    console.error(err);
    res.statusCode = 500
    res.end('internal server error')
  }
});

module.exports = {
  handler
}

奇怪的现象 #

用local-lambda本地测试Lambda处理程序，报错和部署到AWS上一致。但.next/standalone目录自带的server.js，配置和我的handler几乎一样，只是多启动了一个HTTP服务器，却能正常处理所有接口请求，包括OG图片生成的Edge接口。

错误日志更新 #

更新1：初始AWS Lambda错误日志 #

ERROR  [Error [CompileError]: WebAssembly.compile(): Compiling function #64 failed: invalid value type 'Simd128', enable with --experimental-wasm-simd @+3457 ]

更新2：切换Node版本后的新错误 #

把AWS Lambda的Node版本换成16后，上面的错误消失，但出现新的报错：

{
  "errorType": "Error",
  "errorMessage": "write after end",
  "trace": [
    "Error [ERR_STREAM_WRITE_AFTER_END]: write after end",
