Reproduction Repository Required

Thanks for opening this issue! To help us investigate, we need a reproduction repository.

Why we need this

Most issues are configuration-specific. Without a repo we can clone and test, we usually cannot diagnose the problem.

How to create a reproduction

  1. Create a new public GitHub repository
  2. Add the minimum files needed to reproduce the issue
  3. Include a .prettierrc or other config files you're using
  4. Edit this issue and add the repository link

Tip: The simpler the reproduction, the faster we can help!

What happens next

  • With a repo: We'll investigate and respond
  • Without a repo: This issue will be automatically closed in 7 days

I Agree, BTW This Issue reproduced any places (includes out of folders)

I did some investigating on my version of cursor (and got some assistance from Claude). It looks like this might be an ESM support issue in Cursor as the difference between this extension and other extensions appears to be that the ones that work are in CJS and this extension is in ESM.

The key here seems to be at resolve (/Applications/Cursor.app/Contents/Resources/app/node_modules/import-in-the-middle/hook.js:333:26) where it's trying to resolve "vscode" as an import rather than an engine.

Found this in Cursor that they haven't finished porting support for ESM yet - https://forum.cursor.com/t/cursor-2-1-seems-to-lack-esm-extension-support/144434

It's weird that VSCode-v1.104.00-based Google Antigravity supports ESM and works well with the new prettier extension while VSCode-v1.105.1-based Cursor does not.

I also asked Claude Code to fix the bundled extension files.
