panic.zip -> This is the zip of my project (without node_modules)

We're working on a CMS and recently migrated from Docusaurus. All the files in the folder inside the zip is auto generated from a DB, it could be that I'm doing something wrong in the files but in any case a panic doesn't sound good?

Reproduce Steps

Run npm install and npm run build and you ideally should see the error described in details.

I figured the issue out (it was that I was referencing stuff that wasn't available in the index.md file), once I took care of that the panic went away.

yeah, I also solved this by modifying docs/1.0.0/index.mdx

this is an error from markdown-rs imported from mdx-rs, your markdown did not follow the grammar, resulting in parsing errors.

we'll track the error message handling in web-infra-dev/mdx-rs#49
