This code runs without errors, but cannot add anyone to any roles - discord.js

Question

const { Client, Intents } = require('discord.js');
const { GoogleSpreadsheet } = require('google-spreadsheet');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MEMBERS, Intents.FLAGS.GUILD_MESSAGES] });
const PREFIX = '!';
// Specify your credentials here
const creds = {
client_email: 'myclient',
private_key: 'myprivatekey',
};
client.on('ready', () => {
console.log(`Logged in as ${client.user.tag}!`);
});
client.on('message', async (message) => {
if (!message.content.startsWith(PREFIX) || message.author.bot) return;
const args = message.content.slice(PREFIX.length).trim().split(/ +/);
const command = args.shift().toLowerCase();
if (command === 'assignrole') {
if (!message.member.permissions.has('MANAGE_ROLES')) {
console.error('Error: User does not have the ManageRole permission');
message.reply('You do not have permission to use this command');
return;
}
const sheetId = args[0];
if (!sheetId) {
console.error('Error: Missing spreadsheet ID in command');
message.reply('Please provide a valid spreadsheet ID');
return;
}
const doc = new GoogleSpreadsheet(sheetId);
try {
await doc.useServiceAccountAuth(creds);
await doc.loadInfo(); // loads document properties and worksheets
const sheet = doc.sheetsByIndex[0]; // assumes sheet is first in document
const rows = await sheet.getRows();
const role = message.mentions.roles.first();
if (!role) {
console.error('Error: Missing role in command');
message.reply('Please provide a valid role');
return;
}
const roleName = role.name;
const successfulUsers = [];
for (let i = 0; i < rows.length; i++) {
const row = rows[i];
const user = message.guild.members.cache.find(
(member) => member.user.username === row._rawData[0]
);
if (user) {
try {
await user.roles.add(role);
row._rawData[1] = 'OK';
await row.save();
successfulUsers.push(user.user.username);
} catch (err) {
console.error(`Error: ${err.message}`);
}
}
}
message.channel.send(
`The role ${roleName} was added to the following users: ${successfulUsers.join(', ')}`
);
} catch (err) {
console.error(`Error: ${err.message}`);
message.reply('An error occurred while trying to access the spreadsheet');
}
}
});
client.login('mykey');
This is code was made to access a google sheet, reads column A and adds specified role to Users in column A, then adds 'OK' to column B to users who actually got the roleThis runs without errors, but cannot add anyone to any roles.
How can I change this so that it reads usernames on column A, and adds the role specified in the command?
I tried with a test code that exports whats in column A, and it seems to be reading column A.
I have checked permisions on discord side and the role I was trying to assign was under the bot role.
