does not connect to the server with the installed mod on the TACZ weapon

[lastuniverse]

I make proxies with plugins on node-minecraft-proprotocol

• Servers are always 1.20.1
• Mod Tacz (all versions)
  • https://github.com/mcmoddranchor/tacz/releases
  • https://modrinth.com/mod/taczaddon

It works great:

• vanilla client => proxy => vanilla server
• forge client => proxy => forge server (without mods)
• forge client => proxy => forge server (with mods)

does not work:

• forge client => proxy => forge server (with mods + TACZ)

I initialize something like this (autoVersionForge or forgeHandshake)

        this.#client = mc.createClient(this.#parseOptions(this.#options));
        forge.autoVersionForge(this.#client);
        // forge.forgeHandshake(this.#client);

I also tried to throw it on Server (autoVersionForge or forgeHandshake)

        this.#server = mc.createServer(...)
        forge.autoVersionForge(this.#server);
        // forge.forgeHandshake(this.#server);

in the proxy console (only with Forgehandshake on this.#client)

Chunk size is 129 but only 1 was read ; partial packet : {"name":26}; buffer :1a7f7b227472616e736c617465223a22646973636f6e6e6563742e67656e65726963526561736f6e222c2277697468223a5b22496e7465726e616c20457863657074696f6e3a206a6176612e6c616e672e4e756d626572466f726d6174457863657074696f6e3a20466f7220696e70757420737472696e673a205c225c22225d7d

in the server console (only at autoVervationforge on this.#client)

[03:00:47] [Netty Epoll Server IO #14/ERROR] [ne.mi.ne.NetworkRegistry/NETREGISTRY]: Channels [tacz:handshake,tacz:network] rejected vanilla connections

Tell me what can I do to work with Tacz?
Is it possible to use it in the proxy mode?

For the sake of a clean experiment, I took the code from readme.md

app.js

var mc = require('minecraft-protocol');
var autoVersionForge = require('minecraft-protocol-forge').autoVersionForge;
var client = mc.createClient({
    version: false,
    host: "127.0.0.1",
    port: 25565,
    username: "Ara",
    // password: password
});

autoVersionForge(client);

I installed node-minecraft-protocol-forge like this:

npm install minecraft-protocol-forge

In the package.json of the minecraft-protocol-forge package, the version is 1.0.0.

When running node app.js, I get the following in the Forge server console:

• If there are no mods on the server, the client connects.
• If the tacz mod is on the server, there's an error:

[23:45:07] [Netty Epoll Server IO #5/ERROR] [ne.mi.ne.NetworkRegistry/NETREGISTRY]: Channels [tacz:handshake,tacz:network] rejected vanilla connections
[23:45:07] [Netty Epoll Server IO #5/INFO] [ne.mi.se.ServerLifecycleHooks/SERVERHOOKS]: [/127.0.0.1:38674] Disconnecting VANILLA connection attempt: This server has mods that require Forge to be installed on the client. Contact your server admin for more details.

I installed node-minecraft-protocol-forge like this (latest commit from Git):

npm i PrismarineJS/node-minecraft-protocol-forge#d723566a5627b220a99e136b4b9cbc453c62e8bc

In the package.json of the minecraft-protocol-forge package, the version is 1.1.0 (apparently the latest beta commit, because there's no release tag).

When running node app.js, I get the following in the Forge server console:

• If there are no mods on the server, there's an error:

[23:48:29] [Server thread/INFO] [minecraft/MinecraftServer]: Ara joined the game
[23:51:09] [Server thread/INFO] [minecraft/ServerGamePacketListenerImpl]: Ara lost connection: Disconnected
[23:51:09] [Server thread/INFO] [minecraft/MinecraftServer]: Ara left the game
[23:54:14] [Netty Epoll Server IO #3/ERROR] [ne.mi.ne.HandshakeHandler/FMLHANDSHAKE]: Recieved unexpected index 0 in client reply

• If the tacz mod is on the server, the error is the same as with version 1.0.0:

[23:56:04] [Server thread/INFO] [ne.mi.se.pe.PermissionAPI/]: Successfully initialized permission handler forge:default_handler
[23:56:14] [Netty Epoll Server IO #1/ERROR] [ne.mi.ne.HandshakeHandler/FMLHANDSHAKE]: Recieved unexpected index 0 in client reply

Please, I kindly ask you to add support for complex mods like tacz to the package, or explain how I can add it myself. I haven't been able to figure it out on my own even after a day. I couldn't even understand whose responsibility this is: the node-minecraft-protocol-forge package, or if I need to add protocol data descriptions for the tacz mod to minecraft-protocol itself.

????????????????? fml:handshake

At this moment it freezes about 30 seconds then the client falls off.

Here is a piece of code where it happens

        case 'fml:handshake': {
          debugLog('\n\n?????????????????', 'fml:handshake');
          
          const { data: handshake } = proto.parsePacketBuffer(
            PROTODEF_TYPES.HANDSHAKE,
            loginwrapper.data
          )
          debugLog('\n\n!!!!!!!!!!!!!!!!!', handshake.discriminator);

It is obvious that he can not steam the buffer with Messageid: 2
I really understand where and how to look for information about the insides of the protocol, I tried to watch Forge sources, but for me this is a dark forest.

I’ll probably finish this, I hope that the features I have found will help someone to finalize this module.
