var StoreSchema = new Schema({
  name: String,
  user : [{ type: Schema.Types.ObjectId, ref: 'User' }] 
});

This actually defines a one to many relationship between store and user as well. Is that intentional? If not you should remove the [, ] from around user, as well as in save().

Check to make sure that req.session._id has a valid mongoose Object ID, that is the mostly likely reason that the save is not working.
