The line that the error pops up :

                        console.log(inventory.length);
                        for(let l = 0 ; l < inventory.length; l++) {
                            if(inventory[l].market_hash_name == prices[i].name) itemid = inventory[l].assetid;
                        }

So I cant call my inventory if I called it a few seconds ago?

You could use Try Catch for error handling.
