`get_installed_servers()` does not return all installed servers when starting up Neovim

[kamalsacranie]

Problem description

I refer to require("nvim-lsp-installer") as lsp_installer for brevity.

I use lsp_installer.get_installed_servers() when setting up LSP and use the name table entry for each one to dynamically create a list of installed LSP clients. I run the following when initialising nvim:

...
local servers = {}
for i, server in ipairs(require("nvim-lsp-installer").get_installed_servers()) do
    servers[i] = server.name
end
...

I know that I have the servers { "texlab", "bashls", "pyright", "html", "grammarly", "prosemd_lsp", "r_language_server", "sumneko_lua", "emmet_ls" } installed (included in screenshot) but when using the above code print(vim.insepct(servers)) (run after the for loop above) yields the output of only

{ "html", "grammarly", "prosemd_lsp", "r_language_server", "sumneko_lua", "emmet_ls" }

I.e., function get_installed_servers() does not return all servers I have installed.

Interestingly, when I am in the LSP file which sets up my server and run :so %, the function then yields all the correct servers. I.e., once Neovim has completely initialised and I have entered the buffer, the functions works as intended.

Hopefully you can reproduce this error and that it is not a problem with my cofig :laughing

Hello! Hmm, I'm unable to reproduce this. Could you set the log level to TRACE and provide the trace logs:

:LspInstallLog
:%!grep 'TRACE'
:%y

[williamboman]

You'll need to change the trace log level :h nvim-lsp-installer-debugging

require("nvim-lsp-installer").setup {
  log_level = vim.log.levels.TRACE
}

[kamalsacranie]

I just realised!! how embarrassing...

I was calling require("nvim-lsp-installer").setup() after trying to get the server names. When I set TRACE on I called setup() before the require("nvim-lsp-installer").get_installed_servers() call.

Calling setup before fixed the issue. Sorry for the waste of time!!

[williamboman]

Ah cool! Bit weird, as calling setup shouldn't have any impact on what those functions return. Let's reopen if you run into issues again

@williamboman I'm actually having a similar problem. Calling require('nvim-lsp-installer').get_installed_servers() returns nil for me.
