Discord.js v12 MemberList 命令

Question

我有这个 memberlist 命令可以工作，但我遇到了问题。我没有收到任何错误，尽管它总是会发送 if(!members) 报价并且不会给我实际的成员列表。请帮忙谢谢

module.exports = {
    name: 'memberlist',
    description: 'shows the member list with the specified role',
    async execute(message, args, Discord) {
        const role = message.guild.roles.cache.get(args[0]);
        const embe = new Discord.MessageEmbed()
        .setDescription(`${message.author.username} Mention the role or put the role ID`)
        .setColor("RANDOM")
        .setTimestamp()
      if(!role) return message.channel.send(embe); 
        const rid = message.content.split(' ').splice(1).join(' ');
        const rrole = message.guild.roles.cache.find(val => val.id === rid);
        if (!rrole) return message.channel.send({embed: {description: `${message.author.username} 
\`${rid}\` is not a role on this server`, color: "RANDOM", timestamp: new Date()}});
        const members = await message.guild.members.fetch().then((members) => {
            if (Array.isArray(members)) {
              return members(
                (member) =>
                `• **${members.displayName}**
                      (${members.username} - ${member.user.id})`
              )
            } else {
              return `• **${members.displayName}**
                           (${members.username} - ${member.user.id})`
            }
          })
        if(!members)
        return message.channel.send({embed: {description: 
`there are no members that currently have **${role.name}** role`, color: "RANDOM", timestamp: new Date()}});
        const embed = new Discord.MessageEmbed()
        .setColor("RANDOM")
        .addField({
            name: `List of ${members}`,
            value: `${members}
            that have the role \`${role.name}\``,
            description: members,
            maxPerPage: 20,
            page: Number(message.arg),
        });
        message.channel.send(embed)
    }
}
