MalformedXML: The XML you provided was not well-formed or did not validate against our published schema

I am having this weird issue while working with AWS S3. I am working on application by which I can store the images to AWS bucket. Using Multer as middleware and S3FS library to connect and upload to AWS.

But the following error pops up when I try uploading the content.

“MalformedXML: The XML you provided was not well-formed or did not validate against our publis hed schema”

Index.js

var express = require('express');
var router = express();
var multer = require('multer');
var fs = require('fs');
var S3FS = require('s3fs');
var upload = multer({
  dest: 'uploads'
})
var S3fsImpl = new S3FS('bucket-name', {
  region: 'us-east-1',
  accessKeyId: 'XXXXXXXXXXXX',
  secretAccessKey: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
});

/* GET home page. */
router.get('/', function (req, res, next) {
  res.render('profile', {
    title: 'Express'
  });
});

router.post('/testupload', upload.single('file'), function (req, res) {
  var file = req.file;
  console.log(file);

  var path = req.file.path;
  var stream = fs.createReadStream(path);
  console.log(stream);

  S3fsImpl.writeFile(file.name, stream).then(function () {
    fs.unlink(file.path, function (err) {
      if (err) {
        console.log(err);
      }
    });
    res.redirect('/profile');
  })
});

module.exports = router;

Answer

This code should work for you. You need to remember that: 1) use unique bucket name 2) under your file object use ‘originalname’ instead of ‘name’ <– this property does not exist

app.post('/testupload', function(req, res){


    var file = req.files[0];

    console.log(file.path);
    console.log(file.name);

    console.log('FIRST TEST: ' + JSON.stringify(file));

    var stream = fs.createReadStream(file.path);    

    S3fsImpl.writeFile(file.originalname, stream).then(function () 
      {
        console.log('File has been sent - OK');
      },
      function(reason)
      {
          throw reason;
      }
     ); 

     res.redirect('/index');   

});
