【问题描述】：

Code:
const ModSchema = require('../models/ModSchema');

module.exports = 
    name: 'warns',
    description: "lists a members warns.",
    execute(message, args, client, Discord)
        const UserIDsearch = message.mentions.members.first().id;
        ModSchema.findOne( 'UserID': UserIDsearch , function (err, Punishments) 
            if (err) return console.log(err);
            let data = Punishments;
            console.log(data);
            message.channel.send(data);
        )
    

Error Message:
(node:7397) UnhandledPromiseRejectionWarning: DiscordAPIError: Cannot send an empty message
    at RequestHandler.execute (/Users/mynamegoeshere/ESENTRIX CLONE FILE/Esentrix-Bot-5/node_modules/discord.js/src/rest/RequestHandler.js:154:13)

What I want to send in Discord: 
"Punishments": [
    
      "PunishType": "Mute",
      "Moderator": "Poetic",
      "Reason": "test",
      "Time": "10000 ms"
    

这是用于从 MongoDB 数据库查询数据的代码，数据存储为 JSON 文件，但我认为如果将其设置为 const/let，它会被字符串化。请让我知道如何发送数据，因为我似乎找不到问题。请记住，我尝试发送的文本可以使用 console.log(data); 记录到控制台，但是在使用 message.channel.send(data); 时出现上述错误；如果您需要更多信息，请告诉我。

【参考方案1】：

也许可以试试

module.exports = 
    name: 'warns',
    description: "lists a members warns.",
    execute(message, args, client, Discord)
        const UserIDsearch = message.mentions.members.first().id;
        ModSchema.findOne( 'UserID': UserIDsearch , function (err, Punishments) 
            if (err) return console.log(err);
            if(Punishments)
                let data = Punishments;
                console.log(data);
                message.channel.send(data);
            
        )
    

或者只是为了确保它的字符串化，试试

JSON.stringify(data)
