Detailed description of a problem

After running the code, it displays in the chat. He logs into the server for a split second and then gets kicked. I tried testing on localhost, everything worked, but after connecting to the server I needed, I got an error.

Confirmed bug on 1.20.5+ due to incorrect holderset data type implementation. Will be fixed with #1347.

when is the release?

Nov 25 '24 10:11 MayorLeon20

Depends on when someone finishes the remaining work in the PR

Nov 25 '24 15:11 extremeheat

BlockSet was removed/fixed in 1.21 with new holderSet/holder implementations in node-minecraft-protocol, but 1.20.5 was not updated, https://github.com/PrismarineJS/minecraft-data/pull/948 will fix

if you have this error, can you please provide a packet buffer

const fs = require('fs')
const file = fs.createWriteStream('log.txt')
bot._client.on('packet', (data, meta, buffer) => {
  const x = JSON.stringify([meta, data, buffer.toString('hex')])
  file.write(x + '\n')
})

with log.txt

Temporary fix

In my case, the "partial read error" occurs because the server uses Paper and sends custom packets. This issue is present in Mineflayer version 1.21+ but does not occur in version 1.20.4.

To work around this, I used "ViaProxy," set the server version to 1.21, and kept Mineflayer at version 1.20.4. Then, I connected through the proxy.

This resolved the issue, and the error no longer occurs. Use this workaround until the bug is officially fixed.

It's not custom packets but not implementing all the new Item component types yet.

Contributions welcome in https://github.com/PrismarineJS/minecraft-data/pull/948 - already alot of the work is finished
