javascript - Discord.js - if(something === undefined) 问题

Question

我正在为我的不和谐机器人创建索赔订单，所有订单都存储在这样的 json 文件中，{ "mUT": { "orderID": "the order's id", "userID": "A number", "guildID": "another number", "channelID": "another remember", "order": "the order", "status": "Unclaimed", "ticketChannelMessageID": "another another number" }, 但是当使用索赔命令时，它一直说订单不存在，即使我检查了 json 文件并且订单在那里我不太明白这个问题，命令根本不起作用

const colors = require("colors");

exports.id = "claim";

exports.onLoad = api => {
    api.commands.add("claim", (msg) => {
        
        let employeeRole = msg.guild.roles.get("745410836901789749");

        

        if(msg.member.roles.has(employeeRole.id)) {
            if(msg.channel.id == 746423099871985755) {
                // The ticket ID.
                let ticketID = msg.content.substring(7);
                
                fsn.readJSON("./orders.json").then((orderDB) => {
                    const order = orderDB[ticketID];

                    // If the order doesn't exist.
                    if(order === undefined) {
                        msg.reply("Couldn't find that order.");

                        return;
                    }
                    
                    if (order.status === "Unclaimed") {                        
                        // Edits the message in the tickets channel.
