Gives an error setRequired is not a function, there is a function in the documentation, why?

Question

JavaScript

The code

const Discord = require('discord.js');
const { SlashCommandBuilder } = require('@discordjs/builders');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('ban')
    .setDescription('Отправляет ваш аватар/аватар упомянутого пользователя')
    .addUserOption(option => option
      .setName('banuser')
      .setDescription('Выберите пользователя'))
      .setRequired(true)
    .addNumberOption(option => option
      .setName('days')
      .setDescription('Количество дней бана, от 0 до 7'))
    .addStringOption(option => option
      .setName('reason')
      .setDescription('Укажите причину'))
      .setRequired(true),
  async execute(interaction) {
    let bUser = interaction.options.getMember('banuser')
    let reason = interaction.options.getString('reason')
    let days = interaction.options.getNumber('days')

        if(!bUser) return interaction.reply({content: 'Укажите пользователя, которого вы хотите забанить!', ephemeral: true})

    if(bUser.id === interaction.user.id) interaction.reply({content: "Вы не можете забанить самого себя!", ephemeral: true}); 

    if (!interaction.guild.me.permissions.has("BAN_MEMBERS")) return interaction.reply({content: "У меня нет прав!", ephemeral: true})
    if (!interaction.member.permissions.has("BAN_MEMBERS")) return interaction.reply({content: "У вас нет прав!", ephemeral: true})

    if (!reason) return interaction.reply({content: "Вы не указали причину!", ephemeral: true})
    if (!days) days = 0

    bUser.ban({reason: reason, days: days})

    const ban_embed = new Discord.MessageEmbed()
     	.setColor('#db0f0f')
     	.addFields(
         	{ name: 'Пользователь', value: `<@${interaction.user.id}>` },
         	{ name: 'Забанил', value: `<@${bUser.id}>` },
         	{ name: 'По причине', value: reason }
    );

    interaction.reply({embeds: [ban_embed]})
  },
};

it would seem that there is a method in the documentation , there are no problems with other methods, but it comes out

mistake

TypeError: (intermediate value).setName(...).setDescription(...).addUserOption(...).setRequired is not a function

Answer 1

setDescription('Выберите пользователя'))- you closed the extra bracket here
