[Python] ERR_INVALID_AUTH_CREDENTIALS when using puppeteer

There is a code in the index.js file:

const { Client, LocalAuth } = require('whatsapp-web.js');
const qrcode = require('qrcode-terminal');

(async () => {
console.log('Starting browser launch...');

try {
const client = new Client({
puppeteer: {
executablePath: '/usr/bin/google-chrome',
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-web-security',
'--ignore-certificate-errors',
'--disable-gpu',
'--disable-dev-shm-usage',
'--remote-debugging-port=9222',
'--disable-software-rasterizer'
],
ignoreHTTPSErrors: true,
dumpio: true
},
authStrategy: new LocalAuth({ clientId: 'exampleSession' }),
});

client.on('qr', (qr) => {
console.log('QR Code received.');
qrcode.generate(qr, { small: true });
});

client.on('error', (error) => {
console.error('Client error:', error);
});

await client.initialize();
console.log('WhatsApp client initialized.');

await new Promise(resolve => setTimeout(resolve, 60000));
await browser.close();
console.log('Browser closed.');
} catch (error) {
console.error('An error occurred:', error);
}
})();


When running on Ubuntu 22 with the command:

xvfb-run -a -s "-screen 0 1024x768x24" node index.js


Everything works as it should, but when running the same file from the python code:

import threading
import subprocess

def start_node_script():
global process

command = ['xvfb-run', '-a', '-s', '-screen 0 1024x768x24', 'node', 'index.js']

# Start process Node.js
process = subprocess.Popen(
command,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
text=True,
bufsize=1,
)

# Reading output in a separate thread
threading.Thread(target=read_process_output, args=(process,), daemon=True).start()

log("Node.js script started", session="server")
return jsonify({"message": "Node.js script started"})


I'm getting an error:

An error occurred: Error: net::ERR_INVALID_AUTH_CREDENTIALS at https://web.whatsapp.com


What could this be related to, where to look and what are the options for fixing the problem?

I was running the file from the console and everything worked as it should. But I don't understand what dependencies need to be passed when running index.js from a python file.
