I have a problem with member.roles.cache.fetch()

import { Client, GatewayIntentBits } from 'discord.js';

const TEST_TOKEN = '';
const TEST_GUILD_ID = '';
const TEST_USER_ID = '';

const client = new Client({
    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildMembers
    ]
});

client.once('ready', async () => {
    const guild = await client.guilds.fetch(TEST_GUILD_ID);
    const member = await guild.members.fetch(TEST_USER_ID);
    console.log(member.roles.cache);

    const testFetchResult = await member.roles.cache.fetch();
    console.log('Fetch result:', testFetchResult);

});

client.login(TEST_TOKEN);
