~> haskell-language-server-wrapper --version
haskell-language-server version: 2.9.0.0 (GHC: 9.10.1) (PATH: /nix/store/mc3zijjh8hxn4rvaaxqdiknaa7xypb2b-haskell-language-server-2.9.0.0/bin/haskell-language-server-wrapper)

Reproduction Steps

I tried this:

1. hx src/Main.hs

I expected this to happen:

lsp completion works

Instead, this happened:

It looks like the language server is taking a long time to start up and respond to the initialize request, around 30s. You can increase the timeout with a languages.toml configuration like so:

[language-server]
haskell-language-server = { command = "haskell-language-server-wrapper", args = ["--lsp"], timeout = 45 }
