lua-language-server exits on start

[Masterkraft0r]

Summary

Hi all!

I'm trying to use the lua-language-server with helix and as soon as i open a lua file the line at the bottom says "Language server exited".

$ lua-language-server --version
3.10.3

$ hx --health lua
Configured language servers:
  ✓ lua-language-server: /home/bbugl/.asdf/shims/lua-language-server
Configured debug adapter: None
Configured formatter: None
Highlight queries: ✓
Textobject queries: ✓
Indent queries: ✓

Reproduction Steps

1. Install lua-language-server via the tar or asdf, both are the same for me
2. Run hx file.lua
3. Read "Language server exited." at the bottom

I can reproduce this. It looks like this is caused by LuaLS/lua-language-server@40fd1d7 - the server sends on startup:

2024-08-12T14:20:50.324 helix_lsp::transport [INFO] lua-language-server <- {"jsonrpc":"2.0","method":"$/hello","params":"world"}

but this is invalid JSONRPC. Section 4.2 https://www.jsonrpc.org/specification requires params to be either an array or an object and we close the server because it sent an invalid JSONRPC notification. This should be reported upstream to lua-language-server

Thank you for reporting this to the proper channels!
