Undefined global for builtins

[ddickstein]

How are you using the lua-language-server?

NeoVim

Which OS are you using?

Linux

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

I think I'm encountering the same issue as #1600. In my case it happens sporadically - reloading a lua file in Neovim will often randomly introduce or resolve this behavior.

I'm running version 3.6.4-1 installed from pacman.

Actual Behaviour

Seeing warnings on all builtins as "undefined global"

Reproduction steps

I'm not sure how to reproduce reliably - it seems to happen somewhat randomly when I load the buffer.

Additional Notes

No response

Log File

(I'm time-constrained at the moment but I plan to add this later)

Ditto - I'm seeing the same problem:

MacOS 12.5.1
NVIM v0.8.0
Sumneko 3.6.3

[zenoli]

Same for me. The problem sometimes disappears when I open certain lua files but it's hard to reproduce consistently.

Ubuntu LTS 22.04
Nvim v0.9.0-dev-47-gcfdb4cbad
Sumneko v3.6.4

Check neovim/nvim-lspconfig#2355

[caldwell-63]

Nothing really helpful there.

In my case, out of all globals, I'm getting warnings only for the type standard function: Undefined global 'type'

Really weird, I can't tell where is the root of the problem, is it the Language Server, nvim-lspconfig, the neovim lsp implementation, or something else.

Please open an issue about it.

I've also had this issue, and for me explicitly extending Lua.workspace.library with one of the meta-directories worked, ie.

nvim_lsp.lua_ls.setup {
    settings = {
        Lua = {
            workspace = {
                library = vim.tbl_extend("keep",
                    -- this will probably vary depending on setup, not sure if plugins like mason even install it.
                    {"/usr/lib/lua-language-server/meta/template"},
                    -- and runtime-directories.
                    vim.api.nvim_get_runtime_file("", true)),
            },
        },
    },
}

(might have undesired consequences, but I haven't found any so far 🤷)

[sumneko]

Please try to startup server with parameters --meta=<WRITEABLE_PATH>.
Maybe it generated meta files failed.

[L3MON4D3]

Ah, yes you're right 👍
cmd = {sumneko_binary, "--logpath", "/home/simon/.cache/lua-language-server/", "--metapath", "/home/simon/.cache/lua-language-server/meta/"} works perfectly, thank you!

I've encountered this when the directory lua-language-server is installed into is not writable by the user. As with the above comment I had to set logpath (or the LS failed to start at all) and metapath (or there would be these undefined global errors).

Perhaps the defaults for logpath and metapath ought to be in a writable directory by default (like $XDG_CONFIG_HOME or $HOME/.cache or on macOS $HOME/Library/Caches?)

[godalming123]

For me when I use lsp-zero I do not get this error but with the kickstart.nvim default config I do? strange

I got same issue in win 11, and fix by this suggession, #1788 (comment)
