Fail to build when importing frontmatter

[gbicou]

Describe the bug

When trying to import { frontmatter } from component, it works fine in dev.

But when trying to build the project it fails with "Module has no exported member 'frontmatter'".

yarn run v1.22.19
$ vue-tsc --noEmit && vite build
src/App.vue:2:23 - error TS2614: Module '"./components/ArticleTest.md"' has no exported member 'frontmatter'. Did you mean to use 'import frontmatter from "./components/ArticleTest.md"' instead?

2 import ArticleTest, { frontmatter } from './components/ArticleTest.md'
                        ~~~~~~~~~~~

Found 1 error in src/App.vue:2
error Command failed with exit code 2.

Even if I add this section to vite-env.d.ts :

declare module '*.md' {
  import type { DefineComponent } from 'vue'
  const component: DefineComponent<{}, {}, any>
  export default component

  import type { Frontmatter } from 'vite-plugin-md'
  export const frontmatter: Frontmatter
}

Still refuse to build...
