LSP fails to bind with a Neovim Buffer

[gmmyung]

Describe the problem

I am not sure if this is a duplicate, but I cannot make arduino-language-server work on neovim.

Hey, please check the conversation for this pull request and see if it works for you:

Same for me. Nothing works.
It doesn't show any errors untill i manually type :LspRestart. And when i do, the error pops up:

Client arduino_language_server quit with exit code 1 and signal 15. Check log for errors: C:\Users\Admin\AppData\Local\nvim-data/lsp.log

Part of my init.lua (every tool has latest updates and they all work flawlessly if used separately):

local lspconfig = require("lspconfig")
lspconfig.arduino_language_server.setup({

  --filetypes = { "c", "cpp", "objc", "objcpp", "arduino" },
  enable = true,
  cmd = {
    "arduino-language-server",
    "-cli-config",
    "C:/Users/Admin/AppData/Local/Arduino15/arduino-cli.yaml",
    "-fqbn",
    "arduino:avr:uno",
    "-cli",
    "C:/Program Files/Arduino CLI/arduino-cli.exe",
    "-clangd",
    "C:/Users/Admin/AppData/Local/clangd/clangd.exe",
    --"esp32:esp32:esp32wroover",
  },
  disabledFeatures = { "semanticTokens" },
}

I followed the fix from here: #199, I was able to get the Arduino LSP working by configuring it like this:

lspconfig.arduino_language_server.setup({
	cmd = {
		vim.fn.expand("~/.local/share/nvim/mason/bin/arduino-language-server"),
		"-clangd",
		"clangd",
		"-cli",
		"/opt/homebrew/bin/arduino-cli",
		"-cli-config",
		vim.fn.expand("~/Library/Arduino15/arduino-cli.yaml"),
		"-fqbn",
		"esp32:esp32:t-beam",
	},
	filetypes = { "arduino" },
	autostart = true,
})

Fixed in #205 . Thank you all for the support! Apologies for being so late in fixing this 🙏
