Reproduction

https://github.com/andy820621/nuxt-content-bug-repo

Description

• After running pnpm build && pnpm preview, opening http://localhost:3000 immediately throws a ReferenceError: _default is not defined error in the browser console
• The exception always originates from a Nuxt-generated client entry chunk (e.g., R9RtyYat.js, around line 274 / 21177 lines in the built bundle), which contains code like const XHe = _default
• However, there is no declaration of const/let/var _default anywhere in the file, causing the bundle to crash before the preview page renders

Additional context

My original project has a more complex Nuxt configuration, and downgrading to @nuxt/content@3.8.0 there makes everything work fine.

In this minimal reproduction, however, even @nuxt/content@3.8.0 still fails with _default is not defined, and only 3.7.1 produces a working fine build.

Thanks for the report @andy820621,
The issue should be fixed in main branch and you try with npm i https://pkg.pr.new/@nuxt/content@1af6adc
