Zip file not inflated properly

[chowdaryrahul]

Followed your basic code example to upload extracted zip to S3-

var bucketUpload = unzipToS3.createClient({
key: '***_', // required
secret: '_', // required
bucket: 'np-dev-minisite-extract', // required
region: 'eu-west-1',
endpoint: 's3-eu-west-1.amazonaws.com',

});
var zipStream = fs.createReadStream('********/workers/Folder1.zip');

bucketUpload(zipStream).on('data', function (file) {
console.log(file);
}).pipe(process.stdout);

The upload is not consistent, for some zip's it upload & for some it doesn't .
And only one file under the zip is getting uploaded, rest all files are ignored.
Am i missing anything?
