Description

Versions

  • mineflayer: 2.24.0
  • server: paper
  • node: 12.18.2

Bot cannot connect to server with protocolsupport, the plugin that lets multiple versions join.

Research direction

Start by reproducing the connection with mineflayer 2.24.0 on Node 12.18.2 against Paper with ProtocolSupport, then inspect the packet parsing path named in the stack trace, especially play.toClient and protodef. Done means the bot connects successfully without the reported PartialReadError.
