Hi, I have some challenges compiling elixir-ls. Iām using Erlang 28.1.1 and Elixir 1.19.2-otp-28 installed with mise on Omarchy 3.1.5. using the latest nvim/lazyvim, I can see the following error generated in the logs in ~/.local/state/nvim/lsp.log.
[ERROR][2025-11-04 11:56:04] ...p/_transport.lua:36 "rpc" "elixir-ls" "stderr" "==> elixir_ls_utils\nCompiling 10 files (.ex)\n"

You can recompile this dependency with "mix deps.compile elixir_ls --force", update it with "mix deps.update elixir_ls" or clean it with "mix deps.clean elixir_ls"\n'
Any idea what might be going on here?
Also, related question: is elixir-ls still supported, and is it better to switch to expert from now on? What are the pros and cons of using expert vs elixir-ls nowadays?
