Javascript Discord.js应用程序Bot重新发送消息

我为Discord编写了一个应用程序Bot（就像这一个），但是如果您回答了问题并重新发送了一封信，则Bot会重新发送完整的应用程序。我不明白为什么机器人会这么做。机器人有一个特殊字符的问题，我试图用utf8参数来解决，但它不能正常工作。我的意思是他有时可以展示，但不是一直都可以

               d.getDate(),

              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');


const applicationFormCompleted = (data) => {
    let i = 0, answers = "";

    }
    client.channels.get(config.channel).send(`\`\`\` ----------NEW-Member---------- \n\n${answers} \nDate of Application: ${dformat} \nName of Applicant: ${data.user.tag}\`\`\``);

以及config.js：

module.exports = {
  token: "",
  prefix: "!",
  channel: "703217993597059073",
  applychannel: "703218013721067550"
};

这段代码有点草率，到处都是，我真的建议改为使用模块，而不是switch语句

无论如何，这是我写的代码，并没有完全完成所有代码，因为我希望您能够：

不过它是基于模块的，而且.apply仅适用于服务器通道，但两者都很容易更改

相关配置json：

{
    "application": {
        "channelId": "704158687375261706",
        "questions": [
            "How's your wife",
            "How many times a day do you",
            "What do you think is the purpose of life"
        ]
    }
}
