Can't attach solidity-lsp for .sol files in neovim

Firtsble solidity-ls installed by mason via neovim command

:LspInstall solidity-ls

wasn't executable from terminal, altough it was shown as an executable one when typing :LspInfo in .sol file. After I installed it manually via npm

npm i solidity-ls -g

This is configuration for solidity-ls

require'lspconfig'.solidity.setup({
    on_attach = on_attach,
})

With this empty configuration however root directory is not found, also solidity-ls is not attached to the file which I guess is just a consequence. LspInfo from .sol file before

After adding root_dir manually in a following way and checking the file via luafile %

require'lspconfig'.solidity.setup({
    on_attach = on_attach,
    root_dir = function(fname)
        return vim.fn.getcwd() 
    end,
})

I get this error

LSP[solidity]: Error SERVER_REQUEST_HANDLER_ERROR: "/usr/share/nvim/runtime/lua/vim/lsp/handlers.lua:86: bad argument #1 to 'ipairs' (table expected, got nil)"

Although :LspInfo shows root_dir is set up solidity-ls still is not attached

LspInfo from .sol file after

LspInfo from .sol file after

Any suggestion how to solve this?

Ubuntu 20.04.3 LTS NVIM v0.7.2

I am new in vim, neovim and lua programming so apologizes in advance in case the question is too silly. Thanks.

First, "solidity-ls" should be installed using the command :

:LspInstall solidity

You can find a complete mapping for mason.lsp-config here.

:LspInstall solidity-ls

Doesn't exist so i assume you used this command instead :

:LspInstall solidity_ls

In that case, you actually installed "vscode-solidity-server" and thus you should had the correct cmd configuration in your setup.

require("lspconfig")["solidity"].setup {
  cmd = { 'vscode-solidity-server', '--stdio' },
}

There is probably another way that consist of configuring the default solidity lsp server to solidity_ls instead of solidity that I am not aware of.

Also, you have to be aware of the fact that "vscode-solidity-server" doesn't provide you with a solc compiler. I recommend you to install solc-select to install the last version of solc.
