ng-file-upload stuck at progress - angularjs

Question

Good night!.. I am a newbie working on MEAN Stack, and I'm trying to upload a picture using the ng-file-upload. This is the angular code:
app.controller('profilePicCtrl', ['Upload', '$scope', '$http',
function(Upload, $scope, $http){
$scope.watch(function(){
return $scope.file
}, function(){
$scope.upload($scope.file);
});
$scope.userID = localStorage.getItem('userID');
$scope.upload = function(file){
console.log("entro en upload");
if(file){
Upload.upload({
url:'api/profile/edit',
method:'POST',
data: {userId: $scope.userID},
file: file
}).progress(function(evt, status){
console.log("dale puej mijo ");
console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
}).success(function(data, status){
console.log('archivo subido');
}).error(function(error){
console.log(error);
})
}
};
}]);
Here is the express code:
module.exports.updatePhoto = function(req, res){
var file = req.file;
var userId = req.body.userId;
console.log("User "+userId+ " is submitting ", file.name);
}
And the last is the server-side code, where I call the controller:
var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();
var profileController = require('./routes/profile-controller');
...
app.post('api/profile/edit', multipartMiddleware, profileController.updatePhoto);
It doesn't go thru the controller, the server never responds. Thanks in advance for your attention.

Answer 1

I had a code that wasn't letting me go into any other method different than 'GET'. This one below was the guilty one:
if(req.method === "GET" || req.method === "POST"){
if(!req.isAuthenticated()) {
res.redirect('/#login');
}else{
return next();
}
}
Instead of the or sentence I had in the if just the req.method==='GET sentence, which was causing my code to go into an infinity loop returning the next() method but not finding one. Now with the or sentence my code goes to the POST methods.
