I'm currently in problem with Discord.js, it's saying: Cannot read property 'guilds' of undefined.

I find it amazing that he makes this mistake to me because I have another file that contains 'guilds' and doesn't make a mistake for me.

code:

const Client = require('../../index').Client
const schema = require('../../model/dashboard');
const jwt = require('jsonwebtoken');
const { jwt_secret } = require('../../config.json');
const { Permissions } = require('discord.js');

module.exports = {
  name: "/getUserGuilds/",
  run: async (req, res) => {
    delete require.cache[require.resolve("../html/getUserGuilds.ejs")];

    if (!req.cookies.token) return res.redirect('/login')
    let decoded;
    try { 
        decoded = jwt.verify(req.cookies.token, jwt_secret);
    } catch (e) { }
    if (!decoded) res.redirect('/login');

    let data = await schema.findOne({
        _id: decoded.uuid,
        userID: decoded.userID
    });
    if (!data) res.redirect('/login');

    let guildArray = await process.oauth.getUserGuilds(data.access_token);
    let mutualArray = [];
    guildArray.forEach(g => {
        g.avatar = `https://cdn.discordapp.com/avatars/${g.id}/${g.icon}.png`;
        if (Client.guilds.cache.get(g.id)) {
            const bitPermissions = new Permissions(g.permissions_new);
            if (bitPermissions.has(Permissions.FLAGS.MANAGE_GUILD) || bitPermissions.has(Permissions.FLAGS.ADMINISTRATOR) || Client.guilds.cache.get(g.id).ownerID == data.userID) g.hasPerm = true
            mutualArray.push(g);
        } else g.hasPerm = false;
    });
    let args = {
        avatar: `https://cdn.discordapp.com/avatars/${data.userID}/${data.user.avatar}.png`,
        username: data.user.username,
        discriminator: data.user.discriminator,
        id: data.user.userID,
        loggedIN: true,
        guilds: guildArray,
        adminGuilds: mutualArray
    };

    res.render('./website/html/getUserGuilds.ejs', args);

    
  }
}

I initialized in my index.js the constant 'Client' where in it I added the 'intents' and the 'allowedMentions'. I had no problem with the other files a by this one.

const Discord = require("discord.js");
const Client = new Discord.Client({
intents: [
    Discord.Intents.FLAGS.GUILDS,
    Discord.Intents.FLAGS.GUILD_MEMBERS,
    Discord.Intents.FLAGS.GUILD_MESSAGES,
    Discord.Intents.FLAGS.DIRECT_MESSAGES,
],
allowedMentions: {
    parse: ['users', 'roles'],repliedUser: true,
 }
});

Thank you for your answers.
