我一直在尝试使用 lambda 支持的自定义资源。我正在尝试使用自定义资源触发 Lambda 函数。在堆栈创建时，自定义资源挂在 CREATE_IN_PROGRESS 上，但我能够收到电子邮件，并且在尝试删除堆栈时，它卡在 DELETE_IN_PROGRESS 上。

现在我有五个堆栈挂在 DELETE_IN_PROGRESS 上。自定义资源在哪里创建？

     "SendEmailNotification" : {
        "Type": "AWS::Lambda::Function",
        "Properties": {
            "Handler": "index.handler",
            "Role": { "Fn::GetAtt" : ["LambdaExecutionRole", "Arn"] },
            "Code": {
                "ZipFile":  { "Fn::Join": ["", [
                    "var aws = require('aws-sdk');\n",
                    "var response = require('cfn-response');",
                    "var ses = new aws.SES({\n",
                    "region:'us-east-1'\n",
                    "});\n",
                    "exports.handler = function(event, context) {\n",
                    "console.log('Incoming: ', event);\n",
                    "var eParams = {\n",
                    "Destination: {\n"  ,
                    {"Fn::Join" : ["",["ToAddresses: ['",{ "Ref" : "EmailId" },"']\n"]]},
                    "},\n",
                    "Message: {\n",
                    "Body: {\n",
                    "Text: {\n", …

首先，我试图将文件复制到其他文件夹中，但无法删除它。只有将文件复制到目标文件夹时，我才能删除文件。

    const s3Params = {
        Bucket: bucket,
        CopySource: bucket + '/' + objectkey,
        Key: 'processed-data/' + objectkey
    };

    function copyFile() {
        s3.copyObject(s3Params, function (err, data) {
            if (err) {
                console.log(err);
            }
            else {
                deleteFile();
            }
        });
    }

    function deleteFile() {
        s3.deleteObject(s3Params, function (err, data) {
            if (err) {
                console.log(err, err.stack);
                logs.push(err, err.stack);
            }
            else {
                console.log("File moved successfully");
                log.push("File moved successfully");
            }
        });    
    }
