SyntaxError: Unexpected token '.'

I getting an error when running the program in repl.it, even though on my personal laptop the application runs smoothly but for some reason when I run it on repl.it it gets an error like the text above.

I've made sure there's nothing wrong, but when I run it in repl.it it gets an error, here's my code:

    require('./config')
    const { default: makeWASocket, useSingleFileAuthState, DisconnectReason, generateForwardMessageContent, prepareWAMessageMedia, generateWAMessageFromContent, generateMessageID, downloadContentFromMessage } = require("@adiwajshing/baileys-md")
    const { state, saveState } = useSingleFileAuthState(`./${sessionName}.json`)
    const pino = require('pino')
    const fs = require('fs')
    const chalk = require('chalk')
    const fetch = require('node-fetch')
    const FileType = require('file-type')
    const http = require('http');
    const express = require('express');
    const { imageToWebp, videoToWebp, writeExifImg, writeExifVid } = require('./lib/exif')
    const { smsg, isUrl, generateMessageTag } = require('./lib/myfunc')
    const app = express();
    app.use(express.json());
    
    app.use('/', function(req, res) {
        res.send('node-ex-api works!');
    });
    
    const server = http.createServer(app);
    const port = 3000;
    server.listen(port);
    
    console.debug('Server listening on port ' + port);
    
    global.api = (name, path = '/', query = {}, apikeyqueryname) => (name in global.APIs ? global.APIs[name] : name) + path + (query || apikeyqueryname ? '?' + new URLSearchParams(Object.entries({ ...query, ...(apikeyqueryname ? { [apikeyqueryname]: global.APIKeys[name in global.APIs ? global.APIs[name] : name] } : {}) })) : '')

        })

        asrbot.ev.on('connection.update', async (update) => {

I have marked the error line (at the bottom of my script)
