Upgraded to fumadocs 12 -> 13.4; Getting `ShikiError`'s on build

[ndom91]

To Reproduce

With this branch I can no longer build my Fumadocs project.

To reproduce:

1. Clone repo and install deps
2. run pnpm build
3. Error

Webpack initial complains about not being able to serialize the error, and then we see the actual error message:

Specifically it's complaining about these files:

• content/docs/development/debugging.mdx
• content/docs/features/virtual-branches/signing-commits.mdx
• content/docs/troubleshooting/recovering-stuff.mdx

These are the only 3 files using ``bash code blocks, so that much makes sense. They're not using any additional highlighting or notation or any feature other than atitle="Terminal"` annotation.

I used your fumadocs docs site as a "template" when upgrading, so the shiki libs I have installed are:

• shiki@1.16.1
• @shikijs/transformers@1.16.1

Below are my source and source.config files

app/source.ts

```ts import { meta, docs } from "@/.source" import { createMDXSource } from "fumadocs-mdx" import { loader } from "fumadocs-core/source" import { attachFile, createOpenAPI } from "fumadocs-openapi/server" import type { InferMetaType, InferPageType } from "fumadocs-core/source" export const utils = loader({ source: createMDXSource(docs, meta), pageTree: { attachFile } }) export const openapi = createOpenAPI({}) export type Page = InferPageType export type Meta = InferMetaType ```

source.config.ts

```ts import { defineConfig, defineDocs } from "fumadocs-mdx/config" import remarkYoutube from "remark-youtube" import { remarkHeading, remarkImage, remarkStructure, rehypeCode } from "fumadocs-core/mdx-plugins" export const { docs, meta } = defineDocs({ docs: {} }) export default defineConfig({ lastModifiedTime: "git", mdxOptions: { rehypeCodeOptions: { inline: "tailing-curly-colon", themes: { light: "catppuccin-latte", dark: "catppuccin-mocha" } }, remarkPlugins: [remarkHeading, remarkImage, remarkStructure, remarkYoutube], rehypePlugins: (v) => [rehypeCode, ...v] } }) ```
