running wasm-language-server on vscode.dev

Extension sample

wasm-language-server

VS Code version

1.105.1

What went wrong?

When trying to run npm run esbuild as per the instructions, it results in

$ npm run esbuild

> wasm-language-server@1.0.0 esbuild
> node ./bin/esbuild.js

✘ [ERROR] Could not resolve "vscode-languageclient/node"

    client/src/extension.ts:7:82:
      7 │ ...geClientOptions, ServerOptions, RequestType } from 'vscode-languageclient/node';

  The path "./node" is not currently exported by package "vscode-languageclient":

Switching the import line in question from 'vscode-languageclient/node' to

import { LanguageClient, LanguageClientOptions, ServerOptions, RequestType } from 'vscode-languageclient';

gets further, allows npm run esbuild then npm serve then in the command palette install extension from location, things install. Activation seems to begin/log message 'Starting WASM based LSP server'
when a codespace from a git repository is open which seemed like some kind of necessary condition to have a workspace open.

Unfortunately activation fails with:

LSP Client client: couldn't create connection to server.

Sadly, that change seems to break the local install method (within vscode run on the desktop) with the same error so while it makes it compile, it seems incorrect... Curious is anyone has managed to get that sample working on vscode.dev
