Discord.js:TypeError:无法读取未定义的属性“删除”

我在从message.mentions.roles.first()和message.mentions.members.first()中获取正确的信息时遇到麻烦

这是我在Index.js中的命令处理程序

bot.on('message', async (message, guild, helpList, roles) => {
    if (!message.content.startsWith(prefix) || message.author.bot || !message.member.hasPermission('MANAGE_ROLES')) return;
    const args = message.content.slice(prefix.length).split(' ') ;
    const command = args.shift().toLowerCase();
    const aRole = message.mentions.roles.first();
    const Role = aRole.id
    const name = args.join(' ');
    const User = message.mentions.members.first();

    if (!Role && command !== 'create' && command !== 'give' && command !== 'take' && command !== 'help' && command !== 'list') {return message.channel.send('Sorry, that role was not found.')}
    if (!User && (command == 'give' || command == 'take') ) {return message.reply ("That name doesnt match a user.");}

    try{
      bot.commands.get(command).execute(message, Role, name, User, guild, helpList);
    } catch(e){
      console.log(e)
    }  

});

      bot.commands.get(command).execute(message, Role, name, User, guild, helpList);
    } catch(e){
      console.log(e)
    }  

});

这是我的take.js,这是一个从指定成员中删除角色的命令。

module.exports = {
    name: 'take',
    description: '',
  execute(message, Role, User, roles){ 
     try{
    User.roles.remove(Role);
        return message.channel.send (`${Role} has been removed from  ${User}'s list of rolls.`);
      }catch(e){
          console.log(e);
          console.log(Role)
          console.log(User)
      }}}

这是我得到的错误。

为什么角色不起作用?任何帮助是极大的赞赏。
