我为我的不和谐机器人定制的欢迎频道功能不起作用，它看起来像是MongoDB的问题，但我无法解决

Question

我的Discord机器人的可自定义欢迎频道功能不起作用。我使用MongoDB，这样就可以根据服务器定制它。

有3个相关文件：welcome。js（我的模式文件），guildMemberAdd。js（我的事件文件）和setwelcome。js（我用来设置欢迎频道的命令。）

welcome.js文件：

const mongoose = require('mongoose');


const schema = mongoose.Schema({
    _id: {
    type: String,
    required: true
  },
  welcomeChannelId: {
    type: String,
    required: true
  },
  welcomeText: {
    type: String,
    required: true
  }
});

module.exports = mongoose.model('welcome', schema);

guildMemberAdd。js文件：

const { MessageEmbed } = require('discord.js');
const schema = require('../models/welcome.js')

const welcomeData = {}

module.exports = {
    name: 'guildMemberAdd',
    async execute(member) {
        const g = member.guild;
        const ms = require('ms');
        const timeSpan = ms('10 days');

        //Alt detection
        const createdAt = new Date(member.user.createdAt).getTime();
        const difference = Date.now() - createdAt;

        if (difference < timeSpan) {
            member.send('Bye, alt.');
            member.ban({ reason: 'This is an alt.' });
        }

        //Welcome Users
    
    let data = welcomeData[member.guild.id]
    if (!data) {
      const results = await schema.find({
        _id: member.guild.id
      })
      if (!results) {
        return
      }

      const { welcomeChannelId, welcomeText } = results
      const channel = member.guild.channels.cache.get(welcomeChannelId)
      data = welcomeData[member.guild.id] = [channel, welcomeText]
    }

    data[0].send({
      content: data[1].replace(/@/g, `<@${member.id}>`)
    })


    },
};

setwelcome.js文件

const { MessageEmbed } = require('discord.js');
const schema = require('../../models/welcome.js')

module.exports = {
    name: 'setwelcome',
    description: 'Sets the welcome message for the server.',
  options: [{
    name: 'channel',
    description: 'The channel to set as the welcome channel.',
    type: 'CHANNEL',
    required: true
  },
  {
    name: 'message',
    description: 'The welcome message.',
    type: 'STRING',
    required: true
  }],
    async execute(interaction) {
        const channel = await interaction.options.getChannel('channel')
    const message = await interaction.options.getString('message')

    if (
            channel.type !== 'GUILD_TEXT' &&
            channel.type !== 'GUILD_NEWS' &&
            channel.type !== 'GUILD_NEWS_THREAD' &&
            channel.type !== 'GUILD_PUBLIC_THREAD' &&
            channel.type !== 'GUILD_PRIVATE_THREAD'
        )
            return interaction.reply('That is not a valid channel type.');


    await schema.findOneAndUpdate({
      _id: interaction.guild.id,
    },
    {
      _id: interaction.guild.id,
      welcomeChannelId: channel.id,
      welcomeText: message   
    },
    {
      upsert: true
    })

    await interaction.reply(`Welcome channel is set to ${channel} and welcome message is set to \`${message}\`.`)
    },
};

当新成员加入公会时，会抛出以下错误：

 /home/runner/MultiBot/events/guildMemberAdd.js:38
 data[0].send({
            ^

TypeError: Cannot read properties of undefined (reading 'send')
    at Object.execute (/home/runner/MultiBot/events/guildMemberAdd.js:38:13)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

请帮帮我，提前感谢！

Answer 1

将const{WelcomChannelId， WelcomText}=结果替换为const{WelcomChannelId， WelcomText}=结果[0]，因为结果是一个数组

或

使用constresults=wait模式。findOne（{u id:member.guild.id}）只有一个对象才能有结果

Answer 2

这可能是因为数据是数组/对象，没有发送方法。您需要先找到频道，然后再发送类似的内容

js prettyprint-override">const channel = await client.channels.fetch(welcomeChannelId);

Answer 3

这意味着消息无效。确保论点确实存在。有3种方法：

1. 使斜杠命令选项必需（推荐）
2. 如果没有找到参数，则提前返回

if (!message) return; //after the 'message' declaration

const message = await interaction.options.getString('message') || "Welcome to the server!"
