我一直在尝试为我的 discord.js 机器人创建一个命令命令，当有人使用它没有响应的命令并在控制台中显示此错误“此错误源于在没有 catch 块的情况下抛出异步函数内部，或者通过拒绝未使用 .catch() 处理的承诺。承诺被拒绝的原因是：DiscordAPIError: Invalid Form Body embed.fields[0].value: This field is required" 但是我一直在尝试修复它，但我看不到命令​​代码的代码有什么问题

const colors = require("colors");


function generateID() {
    let ticketGen = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split("");
    let ticketStr = "";

    for(let i = 0; i < 3; i++) {
        ticketStr += ticketGen[Math.floor(Math.random() * ticketGen.length)];
    }

    return ticketStr;
}

exports.id = "order";

exports.onLoad = api => {
    api.commands.add("order", (msg) => {
        // The order.
        let order = msg.content.substring(8);
        let customer = msg.author.id

        fsn.readJSON("./blacklist.json").then((blacklistDB) => {
            let entry = blacklistDB[msg.guild.id];
            
            // Checks is server is blacklisted or not.
            if(entry === undefined) {
                // Gets ticket ID.

欢迎来到 StackOverflow！它只是意味着没有valuein fields[0]。尝试这个：

fields: [{
  name: "Order Description",
  value: order || "None", // Returns None if no order
}, {
  name: "Order ID",
  value: ticketID,
}, {
  name: "Order Status",
  value: ticketID",
}],

更好的解决方案是检查所有需要的变量是否符合您的预期。例如，您可以在代码之前添加此代码：

if (!order) return msg.reply("No order found.");
