Error with computeLeaderboard

[Stijndus]

I get this error

(node:16100) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'fetch' of undefined

When I execute this piece of code
`const Levels = require('discord-xp')

module.exports = {
name: 'leaderboard',
description: 'Displays the servers top 10 leveled users',
async execute(message, args, Discord, client) {
const rawLeaderboard = await Levels.fetchLeaderboard(message.guild.id, 10); // We grab top 10 users with most xp in the current server.

    if (rawLeaderboard.length < 1) return reply("Nobody's in leaderboard yet.");
    
    const leaderboard = await Levels.computeLeaderboard(client, rawLeaderboard, true); // We process the leaderboard.
    
    const lb = leaderboard.map(e => `${e.position}. ${e.username}#${e.discriminator}\nLevel: ${e.level}\nXP: ${e.xp.toLocaleString()}`); // We map the outputs.
    
    message.channel.send(`**Leaderboard**:\n\n${lb.join("\n\n")}`);}

}`
