我正在尝试复制上传到S3存储桶的文件以创建带时间戳的备份.('live'文件会定期覆盖以维护perma-link)

但是,AWScopyObject似乎没有执行.我收到以下错误

 {
       "errorMessage": "Process exited before completing request"
 }

导致此错误的代码如下;

    console.log('Loading function');
var AWS = require('aws-sdk');
var s3 = new AWS.S3();

exports.handler = function(event, context) {
    var srcBucket = event.Records[0].s3.bucket.name;
    var srcKey    = event.Records[0].s3.object.key;
    var dstKey    = srcBucket+'/backup/'+ Date.now() + '-' +srcKey;

    console.log(srcKey);
    console.log(dstKey);

    var copyParams = {
        Bucket: srcBucket,
        CopySource : srcBucket + '/' + srcKey,
        Key: dstKey
    };

s3.copyObject(
    copyParams,
    function (err, data) {
        if (err) {
            console.log("ERROR copyObject");
            console.log(err);
        }
        else {
            console.log('SUCCESS copyObject');
        }
        context.done(); …
