Discord.js - DiscordAPIError: Invalid Form Body embed.fields[0].value: This field is required Error

Question

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说这个错误“这个错误源于在没有捕获的情况下抛出异步函数内部阻止，或者拒绝未使用 .catch() 处理的承诺。承诺被拒绝的原因： DiscordAPIError：无效的表单正文 embed.fields[0].value: This field is required" 但是我一直在尝试修复它，但我看不出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;
}

    api.commands.add("order", (msg) => {

欢迎来到 StackOverflow！这只是意味着fields[0] 中没有value。试试这个：

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：

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