Detailed description of a problem

When the bot tries to say anything on an authenticated java edition server (no plugins) using bot.chat("message") it throws this error

C:\Users\Me\Desktop\MineFlayer\Bot\node_modules\minecraft-protocol\src\client\chat.js:374
      if (!client._session.uuid) throw Error("Chat session not initialized. Can't send chat")
                           ^

What did you try yet?

I tried uninstall mineflayer, mineflayer pathfinder, updating npm, updating node.js, deleting everything but the script that contains the bot and then reinstalling everything.

Did you try any example? Any error from those? I tried the mineflayer example, but changed a few lines so it uses microsoft authentication and takes in commandline arguments for the username/ip/port/password

Your current code

const mineflayer = require('mineflayer')

if (process.argv.length < 4 || process.argv.length > 6) {
  console.log('Usage : node farmer.js <host> <port> [<name>] [<password>]')
  process.exit(1)
}

const bot = mineflayer.createBot({
  host: process.argv[2],
  port: parseInt(process.argv[3]),
  username: process.argv[4],
  //password: process.argv[5],
  auth: 'microsoft'
})

bot.on('chat', (username, message) => {
  if (username === bot.username) return
  bot.chat(message)
})

// Log errors and kick reasons:
bot.on('kicked', console.log)
bot.on('error', console.log)

Expected behavior

after the bot logs into the server and you say something in chat it repeats what you said.

Additional context

I tried asking about how to fix this in the mineflayer discord server and no one was able to figure it out.

I am experiencing the same issue on a fresh install as well. No solution so far, will update if I find something.

edit: try

disableChatSigning: true

This will be fixed with next release for NMP.

I'm still struggling with this issue on the latest version whilst connected to online servers, any advice?
