无法读取未定义的属性'fetchBans'>>

我正在尝试一个新命令，即unban命令。但是，如果我运行下面的代码，我将继续得到Cannot read property 'fetchBans' of undefined。我当前正在使用v12.16.3。

  if(!message.member.hasPermission(["BAN_MEMBERS", "ADMINISTRATOR"])) return message.channel.send("You dont have permission to perform this command!")


    if(isNaN(args[0])) return message.channel.send("You need to provide an ID.")
    let bannedMember = await client.guild.fetchBans(args[0])
        if(!bannedMember) return message.channel.send("Please provide a user id to unban someone!")

    let reason = args.slice(1).join(" ")
        if(!reason) reason = "No reason given!"

    if(!message.guild.me.hasPermission(["BAN_MEMBERS", "ADMINISTRATOR"])) return message.channel.send("I dont have permission to perform this command!")|
    message.delete()
    try {
        message.guild.guild.fetchBans(bannedMember, reason)
        message.channel.send(`${bannedMember.tag} has been unbanned from the guild!`)
    } catch(e) {
        console.log(e.message)
    }

    let embed = new Discord.MessageEmbed()
       .setColor('RANDOM')
       .setAuthor(`${message.guild.name} Modlogs`, message.guild.iconURL)
       .addField("Moderation:", "unban")
       .addField("Moderated on:", `${bannedMember.username} (${bannedMember.id})`)
       .addField("Moderator:", message.author.username)
       .addField("Reason:", reason)

        let sChannel = message.guild.channels.find(c => c.name === "modlog")
        sChannel.send(embed)

我正在尝试一个新命令，这是unban命令。但是，如果我运行下面的代码，则会不断获取无法读取未定义的属性'fetchBans'。我目前正在使用v12.16.3。 if（！message ....
