Language server fails to start with error "unregistered dependency token"

Howdy, I’m new to Elm and while trying to get setup ran into some problems. Hopefully this is an obvious user error, but if not may be a bug.

Expected Behavior

When opening a folder containing a valid Elm project in VSCode we expect the language server to start and for its functions to work.

Current Behavior

When opening a folder containing a valid Elm project (from Elm init) VSCode raises 3 error notifications.

Elm output shows the following logs

[Info  - 9:52:55 PM] Loading Elm tree-sitter syntax from ..\..\..\.vscode\extensions\elmtooling.elm-ls-vscode-2.4.0\server\out\tree-sitter-elm.wasm
[Info  - 9:52:56 PM] No elm.json found
[Error - 9:52:56 PM] Server initialization failed.
  Message: Request initialize failed with message: Attempted to resolve unregistered dependency token: "ElmWorkspaces"
  Code: -32603 
[Error - 9:52:56 PM] Starting client failed
  Message: Request initialize failed with message: Attempted to resolve unregistered dependency token: "ElmWorkspaces"
  Code: -32603 

Steps to Reproduce (for bugs)

This bug may not be reproducible. But for me…

1. Open either a personal project or the elm-spa-example project with vscode.
2. Observe vscode display the three error notifications shown above.

Context

I have not had this working before, I’m new to elm and was trying to get setup when I ran into this issue.

Your Environment

• Elm Extension: 2.4.1 (also appears on 2.4.0)
• Windows 11: Version 10.0.22000 Build 22000
• VSCode: 1.65.2
• Elm: 0.19.1 (Installed with windows package manager, available in PATH)
• Node: v16.14.0

Yeah, we deliberatly don’t index anything in elm-stuff or node_modules folders

I think the trouble starts with not being able to find the elm.json. You end up here, https://github.com/elm-tooling/elm-language-server/blob/b22398b3398b20640cbdd9cc6d6b70a14826b800/src/server.ts#L107, you might want to try to remove elm-stuff and rerun elm init maybe evenelm install (even if that errors without params, it still downloads stuff in the background)
