Thread worker + discord.js not working how to solve [nodejs] problem?

Question

Node.js

Error while running: TypeError [Error]: Cannot use 'in' operator to search for 'SHARDS' in world

index.js

const { Worker } = require('worker_threads')

function runService(workerData) {
  return new Promise((resolve, reject) => {
    const worker = new Worker('./core/core.js', { workerData });
    worker.on('message', resolve);
    worker.on('error', reject);
    worker.on('exit', (code) => {
      if (code !== 0)
        reject(new Error(`Worker stopped with exit code ${code}`));
    })
  })
}

async function run() {
  const result = await runService('world')
  console.log(result);
}

run().catch(err => console.error(err))

core.js

const { workerData, parentPort } = require('worker_threads')
const token = require('../configs/token.json')
const prefixes = require('../configs/prefixes.json')
const fs = require('fs')
const Discord = require('discord.js')
const YWS = new Discord.Client({ partials: ['MESSAGE', 'CHANNEL', 'REACTION'] })

YWS.login(token.token).then(console.log(`${prefixes.core} \x1b[32mClient login successful!\x1b[0m`))

const eventFiles = fs.readdirSync('./core/events').filter(file => file.endsWith('.js'));
console.log(`${prefixes.core} Loaded events: \x1b[32m${eventFiles.length}\x1b[0m`)

for (const file of eventFiles) {
  const event = require(`./events/${file}`);
  if (event.once) {
    var res = YWS.once(event.name, (...args) => event.execute(...args, YWS));
  } else {
    var res = YWS.on(event.name, (...args) => event.execute(...args, YWS));
    
  }
}

parentPort.postMessage({ hello: workerData, test: res })
