javascript - Cannot read "path" property of undefined Nodejs -

here jade file

form(method="post", action="/upload", enctype="multipart/form-data")       input(type="file", name="logname")       button(type="submit") upload 

and index.js file

/* home page. */ router.get('/', function (req, res) {     res.render('fileupload', { title: 'building log file viewer' });  });  var formidable = require('formidable'),     fs = require('fs'),     util = require('util');  /* post file upload */ router.post('/upload', function (req, res) {      var form = new formidable.incomingform();      form.parse(req, function (err, fields, files) {          fs.readfilesync(files.upload.path, function (err, data) {             if (err) throw err;            console.log("test");            })     }); }); 

i keep getting typeerror property property "path" undefined; however, when sumbit code under http.createserver, instead of router.post, works fine. have tried asychronous file reading, , gave me same error. ideas?

please try

fs.readfilesync(files.logname.path, function (err, data){ ... });

instead of

fs.readfilesync(files.upload.path, function (err, data) { ... });
