The fumadocs MDX transformation seems to be off with Turbopack, and some MDX frontmatter appears to be missing.

There is unfortunately no way to satisfy these Package shiki can't be external warnings, because there are two packages each requesting different versions of shiki. The only solution would be to somehow use a combination of fumadocs-core and @shikijs/rehype versions that both use the same version of shiki.

fumadocs-core/dist
The package resolves to a different version when requested from the project directory (3.2.1) compared to the package requested from the importing module (2.5.0).

@shikijs/rehype/dist
The package resolves to a different version when requested from the project directory (2.5.0) compared to the package requested from the importing module (3.2.1).
