Lsp-mode: Vue: "File local-variables error: (error Invalid command list)", no `vls`

[dennismayr]

Describe the bug
When opening .vue files using the lsp backend, I'm getting the following error today, visible on the modeline and Messages buffer:

File local-variables error: (error Invalid command list)

At the same time, lsp does not invoke vls in version lsp-20191221. Reverting back to version lsp-20191219 works fine though

To Reproduce
Create a .vue file, like this:

<template>
  <div>
    <div v-bind:key="todo.id" v-for="todo in todos">
      <!-- go through each todo -->
      <ToDoItem v-bind:todo="todo" v-on:del-todo="$emit('del-todo', todo.id)" />
      <!-- show each individual todo from above-->
    </div>
  </div>
</template>

<script>
import ToDoItem from "./TodoItem.vue";

export default {
  name: "Todos",
  components: { ToDoItem },
  props: ["todos"]
};
</script>
<style scoped></style>

Expected behavior
lsp starts the _vue language server_ (vls), code is highlighted as usual, error messages are shown where applicable

Which Language Server did you use
lsp-20191221

Last Working Version
lsp-20191219

OS
ElementaryOS 5.1 / Ubuntu 18.04

Hello,

Just to help with troubleshooting, i'm getting the same Invalid command list error when trying to start lsp on a plain typescript file (typescript-mode), in a project which had lsp running fine prior to a recent upgrade.

It is caused by missing eslint sever. I will do a fix. Commenting the register call in lsp-eslint.el will fix the issue.

Ok, thanks !

Confirming that cloning https://github.com/microsoft/vscode-eslint in ~/.doom.emacs.d/.local/etc folder and setting

        lsp-eslint-server-command `("node"
                                       ,(concat doom-etc-dir "vscode-eslint/server/out/eslintServer.js")
                                       "--stdio")

gets everything working, with eslint as a bonus :)
