AWS S3: Download media file get corrupted

Hi All,

I am trying to download media file (image or video) from AWS S3 using nodejsaws-sdk module. The file is downloaded but I couldn't open as it looks corrupted. Also noted that file size is not same as source file. Refer below code:

var AWS = require('aws-sdk');

var options = {
accessKeyId: "XXX",
secretAccessKey: "XXX"
};
var s3 = new AWS.S3(options);

var bucketName = 'test-bucket';
var keyName = 'test.jpg';
var params = {Bucket: bucketName, Key: keyName};

var fsModule = "fs";
var fs = require(fsModule);

// This requires when running this code in panel
AWS.util.stream = require('stream');

var writeStream = fs.createWriteStream('D:/test.jpg');
var readStream = s3.getObject(params).createReadStream();

readStream.pipe(writeStream);

I have added aws-sdk node module in my extension folder.

Note:
(1) I can download and open txt file without any issue
(2) If I run this code outside panel context (run in local nodejs server) it works for all type of files including text and media!!

Premiere Pro version: 9.0.0
Extension Type: Panel

Thanks & Regards,
