Hello

I am trying to upload pdf file having size 6 mb. it shows upload sucessfully, but when i go to s3 the size is 5 mb. and file is not opening.

Here is my code

var Uploader = require('s3-streaming-upload').Uploader,
 upload = null;
//this function will upload the file to s3
exports.uploadFile = function (fileReadStream, filename, awsHeader, cb) {

    //set options for the streaming module


upload = new Uploader({
  // credentials to access AWS
  accessKey:  config.aws.accessKey,
  secretKey:  config.aws.secretKey,
  bucket:     'bibliohivepdf',
  objectName: "pdf1/"+filename,
  stream:     fileReadStream,
  objectParams: {
    ACL: 'public-read'
  },
  debug:      true
});

upload.send(function (err) {
  if (err) {
    console.log("Errro"+err);
    console.error('Upload error' + err);
  } else {
   console.log("Sucessfull");
  }
});


};
