使用节点 js 格式从 AWS lambda 发送 Json 数据

如何解决使用节点 js 格式从 AWS lambda 发送 Json 数据

现在我设置了由 SQS 触发的 AWS lambda 系统。我设置了 lambda 使用 nodejs 格式。我很难从 SQS 发送正文消息并发回我的 https 网址。

这是我的代码

const https = require('https')

const data = new TextEncoder().encode(
  JSON.stringify({
    data: 'datasend'
  })
)

const options = {
  hostname: '<my url>',port: 443,method: 'POST',headers: {
    'Content-Type': 'application/json','Content-Length': data.length
  }
}

const req = https.request(options,res => {
  console.log(`statusCode: ${res.statusCode}`)

  res.on('data',d => {
    process.stdout.write(d)
  })
})

req.on('error',error => {
  console.error(error)
})

req.write(data)
req.end()

但它返回错误

2021-07-15T01:48:35.566Z    undefined   ERROR   Uncaught Exception  {
    "errorType": "Runtime.HandlerNotFound","errorMessage": "index.handler is undefined or not exported","stack": [

    ]
}

请帮忙
