如何在discord.js v13中获得具有特定角色的公会的所有成员

Question

我目前正在开发一个 discord.js 机器人，以开始使用 node.js 进行一些练习 我目前在尝试让公会的所有成员担任特定角色时遇到了问题。以下是相关代码：

const { SlashCommandBuilder } = require('@discordjs/builders');
const fetch = require('node-fetch');

module.exports = {
    data: new SlashCommandBuilder()
        .setName("server")
        .setDescription("Get server information"),
    async execute(interaction) {
        const serverInfo = await getServerInfo(interaction);
        await interaction.reply({ embeds: [serverInfo] });
    }
}

async function getServerInfo(interaction) {
    console.log("function called")
    let fetchedMemebers = await interaction.guild.members.fetch()
    let roles = await interaction.guild.roles.fetch()

    const totalMembers = fetchedMemebers.memberCount;
    const adminRole = roles.find(role => role.name === "Admin") //the role to check
    const totalAdmin = adminRole.members.length;
    const serverInfo = { // create the embed
        color: 0x0099ff,
        title: `${interaction.guild.name}\'s Server Information`,
        description: `Members: ${totalMembers}\nAdmins (Members with the "admin" role): ${totalAdmin}\nDate created: ${interaction.guild.createdAt.toDateString()}`,
        author: {
            name: `${interaction.user.username}`,
            icon_url: `${interaction.user.avatarURL()}`,
        },
        timestamp: new Date()
    }
    return serverInfo;
};
 
 


    

我有以下错误：

DiscordAPIError: Invalid Form Body
data.embeds[0].description: This field is required

  code: 50035,
  httpStatus: 400,
  requestData: { json: { type: 4, data: [Object] }, files: [] }
}

是的，我知道这不是我的问题，我也不认为这是我的问题。我知道我的嵌入是正确的。我知道我获取当前公会成员的方式有问题，我通过尝试console.log(totalMembers) 验证了这一点，但你什么也得不到。甚至没有输出。我不确定我在这里做错了什么。有任何想法吗？编辑：根据最新的答案更改了我的代码，尽管发生了同样的错误。另外如果你console.log(adminRole.members.length) 又没有输出了。

使用Role#members 获取成员。请记住，这依赖于缓存，因此请使用Guild.members.fetch() 来缓存它们

await interaction.guild.members.fetch() //cache all members in the server
const role = interaction.guild.roles.cache.find(role => role.name === "Admin") //the role to check
const totalAdmin = role.members.map(m => m.id) // array of user IDs who have the role
const totalMembers = totalAdmin.length // how many users have the role
