'An internal error occurred in your connection.' - while changing worlds

I was trying to make a bot for specific minecraft server but I got an error.
Every time after the bot logs in with the login command ( bot.chat('/login password'); ) It gets kicked instantly (Normaly after logging in, server should transfer you to lobby (different world))

Code:

const mineflayer = require('mineflayer');

const bot = mineflayer.createBot({
    host: 'ip',  
    port: 25565,        
    username: 'name',
    version: '1.21.2'  
});

bot.on("kicked", (r) => {
    console.log(r);
});

bot.on('messagestr', (message) => {
    console.log(message);
    if (message.includes('Verified')) {
        bot.chat('/login password');
}
});

Kick reason:

Do you have any ideas?

This is an issue with the server
