我在 discord.js 中制作頭像機器人時出錯

Question

我想為我的機器人發出一個返回用戶頭像的命令，但我收到一個錯誤：

DiscordAPIError: Cannot send an empty message
    at RequestHandler.execute (C:\Users\Pooyan\Desktop\PDM Bot Main\node_modules\discord.js\src\rest\RequestHandler.js:350:13)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

  httpStatus: 400,
  requestData: {
    json: {
      content: undefined,
      tts: false,
      nonce: undefined,
      embeds: undefined,
      components: undefined,
      username: undefined,
      avatar_url: undefined,
      allowed_mentions: undefined,
      flags: undefined,
      message_reference: undefined,
      attachments: undefined,
      sticker_ids: undefined
    },
    files: []
  }
}

我的代碼：

module.exports = {
    name: 'avatar',
    aliases: ['icon', 'pfp', 'profilepic'],
    permissions: [],
    cooldown: 5,
    description: '!',

    execute(message, args, client, Discord) {

        if (!message.mentions.users.size) {
            return message.channel.send(`**آواتار شما:** ${message.author.displayAvatarURL({ dynamic: true })}`);
        }

        const avatar_list = message.mentions.users.map(user => {
            return ` آواتار**<@${user.id}>** ${user.displayAvatarURL({ dynamic: true })}`;
        });

        message.channel.send(avatar_list);
    }
}

我正在使用 Discord.js v13，節點 16

Collection#map返回一個數組，您嘗試send它。 由於您只能發送一個字符串，您可以使用Array#join方法連接返回的數組：

const avatar_list = message.mentions.users.map((user) => {
  return ` آواتار**<@${user.id}>** ${user.displayAvatarURL({ dynamic: true })}`;
});

message.channel.send(avatar_list.join('\n'));
