Extension fails on startup

[Nezteb]

I have this same problem, except the error I see is "invalid type: null, expected a boolean" instead: (this is with "deno.internalDebug": true)

Starting Deno language server...
  version: 1.35.0 (release, aarch64-apple-darwin)
  executable: /Users/noah/.local/share/mise/installs/deno/1.35.0/bin/deno
Connected to "Visual Studio Code - Insiders" 1.87.0-insider
Cannot set workspace settings: invalid type: null, expected a boolean
[Error - 12:59:53 PM] Server initialization failed.
  Message: Internal error
  Code: -32603 
[Error - 12:59:53 PM] Deno Language Server client: couldn't create connection to server.
  Message: Internal error
  Code: -32603 

This looks similar to #994.

My details:

• vscode_deno version 3.33.3
• VS Code Insiders:

• Deno:

• Mise 2024.2.4 macos-arm64 (2024-02-03) (compatible alternative to asdf)

I've verified that deno is in my path, and I've never had issues with VS Code and any other CLI tools.

> which deno
/Users/noah/.local/share/mise/installs/deno/1.35.0/bin/deno

Even setting deno.path doesn't seem to fix it:

"deno.path": "~/.local/share/mise/installs/deno/1.35.0/bin/deno"

EDIT: I guess 1.35.x is just cursed? I couldn't get any of them to work, but bumping up to 1.40.x I can't reproduce this. Soooooo, I'm good to go now? 😅

Had the same issue on 1.31.x. Bumping up to 1.41.0 fixed it for me.

Run deno upgrade, or downgrade the extension according to https://github.com/denoland/vscode_deno?tab=readme-ov-file#compatibility.
