重新启动机器人后，Discord 角色机器人不再提供角色

Question

这是命令代码，机器人在对某个表情符号做出反应后会给你一个角色，但在你重新启动后它就停止监听旧消息，迫使我创建一个新消息：

module.exports = {
name: "reactionrole",
description: "Pone un mensaje con roles por reacción",
async execute(message, args, Discord, client) {
    message.delete();
    
    if (!message.member.hasPermission("MANAGE_MESSAGES")) return message.reply("Negative! You don´t have permissions to do that.")
    
    const channel = "805195024173367327";
    const MemberRole = message.guild.roles.cache.find(role => role.name === "Member");
    const EuropeRole = message.guild.roles.cache.find(role => role.name === "Europe");
    const NARole = message.guild.roles.cache.find(role => role.name === "NA");
    const LATAMRole = message.guild.roles.cache.find(role => role.name === "LATAM");

    const EuropeEmoji = "??";
    const NAEmoji = "??";
    const LATAMEmoji = "?";

    let embed = new Discord.MessageEmbed()
        .setColor("#FF0000")
        .setTitle("Welcome to BOT Wally's server")
        .setDescription(`Report in. Hello, I´m BOT Wally, welcome to my server. Please, select your region down below to become a member:\n\n`
        + `${EuropeEmoji} for EUROPE\n`
        + `${NAEmoji} for NA\n`
        + `${LATAMEmoji} for LATAM\n`
        + `\nEnjoy your stay!`);


        
    let messageEmbed = await message.channel.send(embed);

    messageEmbed.react(EuropeEmoji);
    messageEmbed.react(NAEmoji);
    messageEmbed.react(LATAMEmoji);

    client.on("messageReactionAdd", async (reaction, user) => {
       
        if (reaction.message.channel.id == channel) {
            if(user.partial) await user.fetch();
            if(reaction.partial) await reaction.fetch();
            if(reaction.message.partial) await reaction.message.fetch();

            

            if (reaction.emoji.name === EuropeEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.add(MemberRole);
                await reaction.message.guild.members.cache.get(user.id).roles.add(EuropeRole);
                user.send("Hold this position! Gratz, now you're a memeber of my server. You have selected EUROPE, if you wanna change **your region** contact us via support chat.\n-If you wanna know how I work, just **tag me** in the server.\n-If you want further support please head over to **support chat**.\n-Don't forget to read the **rules** channel.");
            }
            if (reaction.emoji.name === NAEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.add(MemberRole);
                await reaction.message.guild.members.cache.get(user.id).roles.add(NARole);
                user.send("Hold this position! Gratz, now you're a memeber of my server. You have selected NA, if you wanna change **your region** contact us via support chat.\n-If you wanna know how I work, just **tag me** in the server.\n-If you want further support please head over to **support chat**.\n-Don't forget to read the **rules** channel.");
            }
            if (reaction.emoji.name === LATAMEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.add(MemberRole);
                await reaction.message.guild.members.cache.get(user.id).roles.add(LATAMRole);
                user.send("Hold this position! Gratz, now you're a memeber of my server. You have selected LATAM, if you wanna change **your region** contact us via support chat.\n-If you wanna know how I work, just **tag me** in the server.\n-If you want further support please head over to **support chat**.\n-Don't forget to read the **rules** channel.");
            }
        } else {
            return;
    }
    
    });

    client.on("messageReactionRemove", async (reaction, user) => {
        if (reaction.message.partial) await reaction.message.fetch();
        if (reaction.partial) await reaction.fetch();
        if (user.bot) return;
        if (!reaction.message.guild) return;

        if (reaction.message.channel.id == channel) {
           
            if (reaction.emoji.name === EuropeEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.remove(EuropeRole);
            }
            if (reaction.emoji.name === NAEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.remove(NARole);
            }
            if (reaction.emoji.name === LATAMEmoji) {
                await reaction.message.guild.members.cache.get(user.id).roles.remove(LATAMRole);
            }
        } else {
            return;
        }
    });
}
}

它运行良好，直到您重新启动，然后停止侦听旧消息。我有另一个命令，它在我的索引中的作用几乎相同，它确实可以处理旧消息。代码：

client.on("messageReactionAdd", async (reaction, user)=> {

if(user.bot) return;

let ticketid = await settings.get(`${reaction.message.guild.id}-ticket`);

if(!ticketid) return;

if(reaction.message.id == ticketid && reaction.emoji.name == "?"){
    reaction.users.remove(user);

    reaction.message.guild.channels.create(`ticket-${user.username}`, {
        permissionOverwrites: [
            {
                id: user.id,
                allow: ["SEND_MESSAGES", "VIEW_CHANNEL"]
            },
            {
                id: reaction.message.guild.roles.everyone,
                deny: ["VIEW_CHANNEL"]

            }
        ],
        type: "text", parent: "805191968786612264"
    }).then(async channel => {
        channel.send(`<@${user.id}>`, new Discord.MessageEmbed().setTitle("Welcome to your support ticket").setDescription("Please, write your inquiry in this channel and we'll reply ASAP.").setColor("#FF0000"))
    })
}
    
});
