claudiajs / AWS:无法在CloudWatch中看到日志，但代码错误

Question

我使用claudia.js用API创建了一个lambda函数。现在我需要原木。Cloudwatch工作，它向我显示包含完整堆栈信息的代码错误。但是，当我使用console.log()时，就没有条目了。

'use strict'
const awsServerlessExpress = require('aws-serverless-express')
const app = require('./app')
const server = awsServerlessExpress.createServer(app)

exports.handler = (event, context) => {
    console.log(4, "Hello World!")
    awsServerlessExpress.proxy(server, event, context)
}

->在云表中没有输出。

‘

use strict'
const awsServerlessExpress = require('aws-serverless-express')
const app = require('./app')
const server = awsServerlessExpress.createServer(app)

exports.handler = (event, context) => {
    conesole.log("Hello World!")
    awsServerlessExpress.proxy(server, event, context)
}

云表输出：

ReferenceError: conesole没有在exports.handler (/var/exports.handler/lambda.js:7:2)中定义

为什么没有显示console.logs？

Answer 1

首先，请检查您的Lambda函数是否授权将日志写入CloudWatch，否则请附加正确的策略，允许将日志写入云表。请查找下面有写入日志的权限的示例策略，

​

{
"Sid" : "YOURSID",
"Effect": "Allow",
"Action": [
"logs:*"
],
"Resource": [
"arn:aws:logs:::*"
]
}
