NodeJS无服务器抛出错误禁止

Question

我在尝试将Express NodeJS应用程序部署到AWS Lambda时出现以下错误。

ServerlessError: Forbidden
      at /Users/name/.nvm/versions/node/v12.16.3/lib/node_modules/serverless/lib/plugins/aws/provider/awsProvider.js:331:27
      at runMicrotasks (<anonymous>)
      at processTicksAndRejections (internal/process/task_queues.js:97:5)

检测该问题的命令是SLS_DEBUG=1 serverless deploy

serverless.yml

service: mail-server
provider:
  name: aws
  runtime: nodejs12.16
  stage: dev
  region: ap-southeast-1
  memorySize: 128
functions:
  app:
    handler: app/app.handler
    events: 
      - http: 
          path: /
          method: ANY
          cors: true
      - http: 
          path: /{proxy+}
          method: ANY
          cors: true

我一直在关注这个教程：https://bitbucket.org/blog/deploy-an-express-js-app-to-aws-lambda-using-the-serverless-framework

下面是分配的策略：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1482712489000",
      "Effect": "Allow",
      "Action": [
        "iam:CreateRole",
        "iam:PutRolePolicy",
        "lambda:CreateFunction",
        "lambda:InvokeAsync",
        "lambda:InvokeFunction",
        "iam:PassRole",
        "lambda:UpdateAlias",
        "lambda:CreateAlias",
        "lambda:GetFunctionConfiguration",
        "lambda:AddPermission",
        "lambda:UpdateFunctionCode",
        "s3:ListBucket"
      ],
      "Resource": [
        "*"
      ]
    }
  ]
}

Answer 1

1. 如果需要任何环境变量将它们传递给函数，请尝试首先检查您的代码。
2. 尝试在完全访问管理员权限的情况下运行函数检查它是否工作(这不是一个好主意，但最好调试权限问题)

{ "Version": "2012-10-17", "Statement": [ { "Action": "*", "Resource": "*", "Effect": "Allow" } ] }

3:尝试从cloud watch更深入地研究日志。
