Discord.js TypeError: Cannot read property 'send' of undefined in a user defined - mongodb

Question

in the code you see below what it do is connect to a mongodb database, and get user ID stored, and works fine, the problem is sending to that user ID a message, here is the code:
const { MongoClient, ReadPreference } = require('mongodb');
const MONGO_URL = 'mongodb://127.0.0.1:27017/';
(async() => {
const mongoClient = await MongoClient.connect(MONGO_URL, {
appname: 'test',
readPreference: ReadPreference.PRIMARY,
useNewUrlParser: true,
});
const db = await mongoClient.db('test');
const changeStream = db.collection('tools').watch([], { 'fullDocument': 'updateLookup' });
changeStream.on('change', (event) => {
tool.findOne({
code: datos,
}, async(err, s) => {
console.log(datos)
const userID2 = s.userID;
if (!s) {
console.log("pin no encontrado")
}
if (userID2 != undefined) {
try {
setTimeout(function() {
console.log("userID2 = " + userID2)
console.log("Event" = event);
console.log("event.updateDescription.updatedFields =" + event.updateDescription.updatedFields)
const user = client.users.cache.get(userID2)
console.log("const user = " + user)
user.send("Resultados del scan: " + "\nEstá el usuario cheat? " + event.updateDescription.updatedFields.cheats + "\nCheats que tiene el usuario: " + event.updateDescription.updatedFields.namecheats)
}), 5000
} catch (e) { console.log("[ERROR]", e) }
} else { return }
});
})
})();
})
And here is the output in console:
651312
userID2 = 794601739960844348
{
_id: {
_data: '82600D5062000000012B022C0100296E5A1004D5046A26D5AE482380F594D10FDC475546645F69640064600CA9A0FE28E8160C78C34E0004'
},

}

const user = undefined
/home/jonh/bot-tool/src/index.js:101
user.send("Resultados del scan: " + "\nEstá el usuario cheat? " + event.updateDescription.updatedFields.cheats + "\nCheats que tiene el usuario: " + event.updateDescription.updatedFields.namecheats)
^

As you can see, in the output, it logs userID2 = 794601739960844348 and the user ID is good, but for some reason it didnt send the message to that user.
I already tried with fetch() and it didnt work.

Answer 1

Use the following code instead:
setTimeout(async function() {
console.log("userID2 = " + userID2)
console.log("Event" = event);
console.log("event.updateDescription.updatedFields =" + event.updateDescription.updatedFields)
const user = await client.users.fetch(userID2)
console.log("const user = " + user)
user.send("Resultados del scan: " + "\nEstá el usuario cheat? " + event.updateDescription.updatedFields.cheats + "\nCheats que tiene el usuario: " + event.updateDescription.updatedFields.namecheats)
}, 5000)
(fetch the user and fix the set timeout)
