`elm make` Fails After Starting Elm Language Server

tmciver-mackey commented 2 years ago

Thank you for the bug report

[X] I am using the latest version of lsp-mode related packages.
[X] I checked FAQ and Troubleshooting sections
[X] You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

Starting lsp in a buffer containing an Elm source file with elm-mode activated causes the following text to be displayed in *lsp-log*:

Command "/home/tim/.nvm/versions/node/v16.4.0/bin/elm-language-server --stdio" is present on the path.

Steps to reproduce

Install elm-laguage-server globally with

npm i -g @elm-tooling/elm-language-server

Create a fresh emacs environment by (re)moving any current emacs configuration and putting the following in a new $HOME/.emacs/init.el:

(require 'package)

(setq package-archives '(("org" . "https://orgmode.org/elpa/")
                         ("gnu" . "https://elpa.gnu.org/packages/")
                         ("melpa" . "https://melpa.org/packages/")))

;; initialize built-in package management
(package-initialize)

;; update packages list if we are on a new install
(unless package-archive-contents
  (package-refresh-contents))

(exec-path-from-shell-initialize)

Start emacs. Run package-list-packages and install elm-mode and lsp-mode. Restart emacs. Open an Elm source file and ensure that elm-mode is activated. Start lsp-mode withM-x lsp. Observe that elm-language-server starts and stays running but produces the error mentioned above in *lsp-log*.

Expected behavior

No error when starting lsp.

Which Language Server did you use?

elm-language-server version 2.4.1.

OS

Linux

Anything else?

I'm running emacs version 28.0.91 installed using Nix.

To me, it looks like something that has to be investigated on the server side first. Can you ask in their channels?

OK, thank you. I've created an elm-language-server issue here.
