Could not parse expression with acorn

[twlite]

Hi, I'm trying to use fumadocs-typescript for doc generation and running the script does generate mdx files from the model file but starting the server throws build error such as

./content/api/discord-player/classes/FFmpeg.mdx?collection=apiDocs&hash=0b073117ba42f06ce012516127e9009a30b255ed64553b5f64eb1af44becff42
FFmpeg.mdx:305:65: Could not parse expression with acorn

Import trace for requested module:
./content/api/discord-player/classes/FFmpeg.mdx?collection=apiDocs&hash=0b073117ba42f06ce012516127e9009a30b255ed64553b5f64eb1af44becff42

./app/api/layout.tsx

content at FFmpeg.mdx:305 is by default until they are piped or a `'data'` or `'readable'` event handler

the declaration comes from nodejs types itself
