Not functioning as of 1.19.3

When I attempt to use the following code

import { InstantConnectProxy } from 'prismarine-proxy'
const proxy = new InstantConnectProxy({
  loginHandler: (client) => {
    console.log(client.username)
    return {
      username: 'ice',
    };
  },
  clientOptions: {
    host: 'localhost',
    version: '1.19.3'
  },
  serverOptions: {
    version: '1.19.3',
    port: 25566
  }
})

proxy.on('incoming', (data, meta, toClient, toServer) => {
  toClient.write(meta.name, data)
})

proxy.on('outgoing', (data, meta, toClient, toServer) => {
  toServer.write(meta.name, data)
})

I fails with the error

Disconnecting client because error TypeError [ERR_INVALID_ARG_TYPE]: Serialization error for play.toClient : SizeOf error for undefined : The "string" argument must be of type string or an instance of Buffer or ArrayBuffer. Received undefined

I am using a lan world with the port 25565, this was also tested with a server

It appears as though this has to do with the respawn packets and commenting out the following lines in instant_connection_proxy.js seems to have fixed it

//toClient.write('respawn', { ...data, dimension })
//toClient.write('respawn', data)
