I'm going to kill myself.
In the nodejs server for my game, there's a function that pushes to an array.
It only works if the array is empty, no matter what type it is.
List of people that know why
- none

I'm intrigued. Can you link to a snippet?

We figured something out
It's not the first one, its the second one that gets inputed into the array that shows up in the array.

@ihatecomputers
itemfunctions.addItem = function(itemname, username) {
User.findOne({username: username}, (err, user) => {
var users = user;
var item = itemfunctions.itemInvTemplate;
var iteminfo = itemfunctions.getItem(itemname);
item.name = itemname;
item.durabilty = iteminfo.durability;
users.inventory.push(item);
User.findOneAndUpdate({username: username}, users, {upsert:true}, function(err, doc){
console.log(err);
console.log("a");
return;
});
});
}

here's where the array is delcared
inventory: [{name: String, durability: Number, metadata: [String]}]

Fixed it, just used mongodb push instead of js push

syntax error, I believe you mean:

people_who_know_why = []

On the plus side, at least you'll be able to push yourself once you understand, then fix it and add others as you tell them how absurd this bug was
