AWS lambda 訂閱的 SNS 主題不起作用

Question

I was creating a lambda function using node js and executing the simple function, in case of the function returns failure need to trigger an email.

1. Lambda Function代碼

exports.handler = async function(event) {
const promise = new Promise(function(resolve, reject) {
  https.get(url, (res) => {
      resolve(res.statusCode)
    }).on('error', (e) => {
      reject(Error(e))
    })
  })
return promise
}  

2. 創建主題並訂閱 email 通知
3. 我已配置配置 -> 權限 - 已配置角色名稱

AWSLambdaSNSTopicDestinationExecutionRole JSON 格式

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sns:Publish",
            "Resource": "arn:aws:sns:xxx-xxxxxx-x:12435693:XXXXXXX"
        }
    ]
}

  "Id": "__default_policy_ID",
  "Statement": [
    {
      "Sid": "__default_statement_ID",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": [
        "SNS:Publish",
        "SNS:RemovePermission",
        "SNS:SetTopicAttributes",
        "SNS:DeleteTopic",

        "SNS:Subscribe"
      ],
      "Resource": "arn:aws:sns:xxxx-2:xxxxxx1:xxxxxx",
      "Condition": {
        "StringEquals": {
          "AWS:SourceOwner": "xxxxxxxx"
        }
      }
    },
    {
      "Sid": "__console_sub_0",
      "Effect": "Allow",
      "Principal": {
        "AWS": [
          "arn:aws:iam::xxxxxx1:root",
          "arn:aws:iam::xxxxxx2:root"
        ]
      },
      "Action": "SNS:Subscribe",
      "Resource": "arn:aws:sns:xxxx-2:xxxxxx1:xxxxxx_TP"
    }
  ]
}

5. Lambda 的 Destination 訂閱了該主題

當我綁定執行 lambda function 以防發生故障時，我沒有得到任何 email。 即使我也嘗試訂閱成功案例的主題，但我沒有收到任何 email。 任何人都可以面對這個問題嗎？

Lambda 的目的地僅用於您的函數的異步調用。 如果您從控制台或正常同步方式運行 function，則不會觸發目標。
