[Bug]: Preview fails because Open CoDesign app bundle is missing the ms module

[mustafa-brainforge]

Description

Preview fails before rendering App.jsx. The app reports a runtime dependency error from inside the Open CoDesign application bundle: Cannot find module 'ms'. This appears unrelated to the design source because the require stack points to /Applications/Open CoDesign.app/.../node_modules/debug/src/common.js.

Steps to reproduce

1. Open Open CoDesign.
2. Open the workspace/design.
3. Click Preview for App.jsx.
4. Observe that preview fails before rendering the design.

Expected behavior

App.jsx should render in the preview window, or source-level JSX/runtime errors should be shown if the design file has a problem.

Actual behavior

Preview executor fails with:

Cannot find module 'ms'
Require stack:

• /Applications/Open CoDesign.app/Contents/Resources/app.asar/node_modules/debug/src/common.js

The design preview does not load.

Thank you for the detailed report, @mustafa-brainforge! This error — Cannot find module 'ms' from /Applications/Open CoDesign.app/…/node_modules/debug/src/common.js — is a packaging issue inside the Electron app bundle, not a problem with your design source (App.jsx).

The debug package depends on ms for time formatting. In your installed v0.1.3 build, the ms module was not bundled into the .asar archive, causing the runtime failure when the preview sandbox loads code that imports debug (likely via a transitive dependency such as puppeteer-core or electron-log).

What you can do:

1. Try the latest release (v0.2.0) — it includes many packaging fixes and may already resolve this missing dependency.
2. If the issue persists on v0.2.0, please provide:
   • The exact install method (e.g. direct download, Homebrew, winget)
   • Whether a clean reinstall (uninstall + delete config) changes the behavior
   • The full error stack trace (more lines above the require stack shown)

Relevant code (for maintainers):

• apps/desktop/package.json — the dependencies field lists puppeteer-core and electron-log, both of which pull in debug → ms. During the Electron build, electron-builder or electron-vite may have missed this transitive dependency.
