discord.js v12 Unban Command

Question

I made a unban command using discord.js v12. I keep getting the same error every time I run it saying DISCORD API ERROR: NOT FOUND. Even though I send a correct user ID or mention

 const Discord = require("discord.js");
    module.exports = {
      name: "unban",
      category: "moderation",
      description: "unban",
      run: async (client, message, args) => {
    
    
    
        let unbanned = message.mentions.users.first() || client.users.resolve(args[0]);
        let reason = args.slice(1).join(" ");
    
        let member = await client.users.fetch(unbanned);
        let ban = await message.guild.fetchBans();
    
    // MESSAGES

    if (!unbanned) {
      let unbaninfoembed = new Discord.MessageEmbed()
        .setTitle("Command: unban")
        .setDescription(
          `**Description:** Unban a member. \n` +
            "**Sub Commands:**\n" +
            "" +
            "**Usage:**\n" +
            "-unban [user] (limit) (reason) \n" +
            "**Examples:** \n" +
            "-unban <@597253939469221891> good guy \n" +
            "-unban 597253939469221891 good guy "
        )
        .setColor("#2C2F33");
      message.channel.send(unbaninfoembed);

      return;
    }

    if (!ban.get(member.id)) {
      let notbannedembed = new Discord.MessageEmbed()
        .setDescription("This user is not banned")
        .setColor("#2C2F33");
      message.channel.send(notbannedembed);

      return;
    }

    if (!message.guild.me.permissions.has("BAN_MEMBERS")) {
      let botnoperms = new Discord.MessageEmbed()
        .setDescription(
          "I do not have permissions, please contact an administrator"
        )
        .setColor("#2C2F33");
      message.channel.send(botnoperms);

      return;
    }

    if (!message.member.permissions.has("BAN_MEMBERS")) {
      let nopermsembed = new Discord.MessageEmbed()
        .setDescription(
          "You do not have permission `BAN MEMBERS` contact an administrator"
        )
        .setColor("#2C2F33");
      message.channel.send(nopermsembed);

      return;
    }

    var user = ban.get(member.id);
    message.guild.members.unban(member);
    let successfullyembed = new Discord.MessageEmbed()
      .setTitle(`${member.tag} has been successfully unbanned.`)
      .setColor("#2C2F33");

    message.channel.send(successfullyembed);
  },
};

I get this error whenever I run the command:

(node:106) UnhandledPromiseRejectionWarning: DiscordAPIError: 404: Not Found
    at RequestHandler.execute (/home/runner/bot/node_modules/discord.js/src/rest/RequestHandler.js:170:25)

(node:106) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Can you help me out? Thanks in advance. This command also only unbans users in the server and not outside it. Is there any way to fix this out?

Answer 1

You're using client.user.fetch() incorrectly. You're providing the variable unbanned which is a user object, and therefore it results in an API error. client.user.fetch() is requesting an id, so instead write client.user.fetch(unbanned.id) .

https://discord.js.org/#/docs/main/stable/class/UserManager?scrollTo=fetch

Since the fetch just outputs a user object, you could use the unbanned variable instead of making the member variable.

Answer 2

我找到了答案，将client.user.fetch(unbanned)替换为let member = await client.users.fetch(args.slice(0).join(" "));
