TypeError: Cannot set properties of undefined (setting 'height')

• [X] The FAQ doesn't contain a resolution to my issue

Versions

• mineflayer: 4.3.0
• server: 1.12.2, mc.reallyworld.ru, type: "null" (see this screenshot), — the problem occurs in the lobby when "checking" the player (for the presence of some cheats?)
• node: 17.1.0

Detailed description of a problem

When passing the server "checking", clientbound parameters are set too early(?), what causes an unhandled exception:

C:\Users\ufgf\node_modules\minecraft-protocol\src\transforms\framing.js:67
          } else { throw e }
                   ^

What did you try yet?

Connect to other servers, and make sure that the problem repeats itself when connecting only to this one

Your current code

const mineflayer = require("mineflayer");

const options = {
  host: "mc.reallyworld.ru",
  port: "25565",
  username: "some_nick",
  version: "1.12.2",
  checkTimeoutInterval: 60000,
};

var bot = mineflayer.createBot(options);
bot.setMaxListeners(0);
themain();

function themain() {
  bot.on("spawn", () => {
    bot.waitForTicks(60);
    console.log("bot.game.levelType: " + bot.game.levelType);
    bot.end();
  });

  bot.on("kicked", (reason) => {
    console.log("bot was kicked: " + reason);
    bot.end();
  });
}

Expected behavior

The bot at least executes console.log() in bot.on("spawn" ... ) or bot.on("kicked" ... )

Have you tried removing checkTimeoutInterval and bot.setMaxListeners(0)?
