unocss: Warning: failed to find vite:css-post plugin. It might be an internal bug of UnoCSS

I’m using pnpm with nuxt 3:

- Operating System: `Windows_NT`
- Node Version:     `v18.9.1`
- Nuxt Version:     `3.0.0-rc.11`
- Nitro Version:    `0.5.4`
- Package Manager:  `pnpm@7.12.2`
- Builder:          `vite`
- User Config:      `-`
- Runtime Modules:  `-`
- Build Modules:    `-`

How can I debug the issue and solve it?
