CollectionFS 503 Service Unavailable - meteor

Question

I need to upload 'on fly' user's image. But i get error 503 Service Unavailable.
user.js
Meteor.subscribe('userImages');
Template.userProfil.events({
'change [name=userPhotoUpload]': function(event) {
event.preventDefault();
FS.Utility.eachFile(event, function(file) {
var newFile = new FS.File(file);
newFile.metadata = {
createdBy:Meteor.userId(),
}
userImages.insert(newFile, function (err, fileObj) {
if (err){
// handle error
} else {
// handle success depending what you need to do
var currentUserId = Meteor.userId();
var imagesURL = {
"profile.userImg": '/cfs/files/userImages/' + fileObj._id + '/' + fileObj.name()
};
Meteor.users.update(currentUserId, {$set: imagesURL});//there I get url and
}
});
});
}
});
router.js
Router.route('/organizer', {
name: 'userProfil',
template: 'userProfil',
data: function() {
var currentUser = Meteor.userId();
return Meteor.user({_id: currentUser});
}
});
user-img.html
<img src="{{profile.userImg}}">
after uploding image i get this err:
http://localhost:3000/cfs/files/userImages/wNjvF8uuN8j6fd8md/exampl2.jpg 503 (Service Unavailable)
But this path is absolutely correct, and after manual reloading page it's work.
How can I solve this problem?

Answer 1

Ok, I found some solution, but I don't think that it's correct way. Maybe someone have better decision?
Changing:
user.js
'change [name=userPhotoUpload]': function(event) {
event.preventDefault();
FS.Utility.eachFile(event, function(file) {
var newFile = new FS.File(file);
newFile.metadata = {
createdBy:Meteor.userId(),
}
userImages.insert(newFile, function (err, fileObj) {
if (err){
// handle error
} else {
var currentUserId = Meteor.userId();
var intervalHandle = Meteor.setInterval(function () {
console.log("Inside interval");
// changes here:
if (fileObj.hasStored("userImages")) {
//checked if image was stored
var imagesURL = {
"profile.userImg": '/cfs/files/userImages/' + fileObj._id + '/' + fileObj.name()
};
Meteor.users.update(currentUserId, {$set: imagesURL});
// if file has stored, stop interval
Meteor.clearInterval(intervalHandle);
}
}, 1000);
}
});
});
}
