Elixir LS fails to start. Not really sure why.

[benbot]

both elixir and mix are available in my path and I installed through :CocInstall coc-elixir

The LS works when using vscode, but not neovim :(

output of :CocInfo

[benbot]

Seeing the same issue on osx :(

[NeuroWinter]

I am also seeing this issue on Ubuntu 20.4 :(

[dylan-chong]

also same issue on macos 13.2.1, m2 macbook

i tried recompiling elixir-ls from scratch using https://github.com/elixir-lsp/coc-elixir#server-fails-to-start (making sure to git pull the latest elixir-ls first)
usually it can help when changing erl/ex/node versions but it didn't this time

EDIT: i found out the elixir ls path in my cocconfig is pointing to the wrong folder. i apparently had a second place where i had cloned elixir ls

after i had fixed the path and recompiled elixir-ls, i get an error [coc.nvim] OTP compiled without EEP48 documentation chunks in vim's message line

i still get the same error though

[islam-taha]

I have been facing the same issue a lot, and I finally managed to solve it using the right erlang/elixir combo according to this table: https://github.com/elixir-lsp/elixir-ls#support-matrix

I was using elixir 1.13.1 & erlang v26, and this was causing the problem, falling back to erlang v24 solved the problem after recompiling everything.
