Puppet langage sever errors out in nvim

[genebean]

Problem description

When I open a puppet manifest (a .pp file), I see this at the bottom of nvim:

LSP[puppet][Warning] An error occurred while starting the Language Server. The server has been disabled.

Running :LspLog opens an empty file. This is confirmed by listing the files in the directory where it seems to expect the log:

$ ls -lh ~/.local/state/nvim/

Checking for puppet in the mason logs shows it installed fine:

$ grep puppet ~/.local/state/nvim/mason.log

Why do you think this is an issue with mason-lspconfig.nvim?

Mason installed the LSP to ~/.local/share/nvim/mason/packages/puppet-editor-services and if I can do this:

$ ~/.local/share/nvim/mason/packages/puppet-editor-services/puppet-languageserver
LANGUAGE SERVER RUNNING localhost:55397

That seems to indicate that the LSP runs and nvim just can't talk to it correctly... I think?

Neovim version (>= 0.7)

I've manually reviewed the Nvim LPS client log (:LspLog) to find potential errors

+1. I will also add that when I manually installed the language server at the same path, neovim started working with it as expected.

[genebean]

Bypassing the shell script in makes it work:

require("lspconfig").puppet.setup {
  cmd = { "/Users/gene.liverman/.local/share/nvim/mason/packages/puppet-editor-services/libexec/puppet-languageserver" }
}

This makes me think it is something about ~/.local/share/nvim/mason/packages/puppet-editor-services/puppet-languageserver that is the issue here.
