I'm using Node.js (v0.10.25) and Express (4.13.1) and using jade instead of HTML. I have a registration form where a user can registrate and upload a profileimage.
All works fine except when I upload an empty image then the I get the following error:
Cannot read property 'profileimage' of undefined

What I have read and tried:
On the USER.JS it give the result "undifned" on the first test and on the second test it fails completely. Also I get nog cosole.log for the else statement in the
if (req.files.profileimage){
console.log('Uploading file....');
//File Info
var profileImageOrginalName = req.files.profileimage.orginalname;
var profileImageName = req.files.profileimage.name;
var profileImageMimetype = req.files.profileimage.mimetype;
var profileImagePath = req.files.profileimage.path;
var profileImageExt = req.files.profileimage.extension;
var profileImageSize = req.files.profileimage.size;
} else{
console.log('profileImageFile not found....');
// Set default image
var profileImageName = 'noimage.png';
}
