index.handler 未定义或未导出 AWS

Question

我有一个 index.js 并且定义了处理函数。但是当我测试时，我得到了错误index.handler is undefined or not exported。知道如何解决这个问题吗？

{
  "errorType": "Runtime.HandlerNotFound",
  "errorMessage": "index.handler is undefined or not exported",
  "trace": [
    "Runtime.HandlerNotFound: index.handler is undefined or not exported",
    "    at Object.module.exports.load (/var/runtime/UserFunction.js:144:11)",
    "    at Object.<anonymous> (/var/runtime/index.js:43:30)",
    "    at Module._compile (internal/modules/cjs/loader.js:999:30)",
    "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1027:10)",
    "    at Module.load (internal/modules/cjs/loader.js:863:32)",
    "    at Function.Module._load (internal/modules/cjs/loader.js:708:14)",
    "    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:60:12)",
    "    at internal/main/run_main_module.js:17:47"
  ]
}

Lambda 函数尚不支持 ES6 风格 (https://docs.aws.amazon.com/lambda/latest/dg/nodejs-handler.html)

你应该使用：

exports.handler =  async function(event, context) {
}
