When I try to spawn elixirls language server using the following config:

require('lazy').setup({ 
  local servers={
      elixirls = {cmd = {"/home/user1/elixir-ls/elixir-ls"}},
    } 
})

I get this error:

/usr/share/nvim/runtime/lua/vim/lsp/rpc.lua:800: Spawning language server with cmd: `{ "/home/user1/elixir-ls/elixir-ls/" }` failed with error message: /usr/share/nvim/
runtime/lua/vim/_system.lua:244: EACCES: permission denied

Edit:

I changed the path to ~/home/user1/elixir-ls/elixir-ls/release/language_server.sh
and it worked.
Now I am facing another problem. A process called beam.smp is consuming 500% of my CPU, I am pretty sure it’s related to elixir-ls
