How can I solve a page crash when using sidebar_custom_props in front matter?

[jkboxomine]

I'm using Docusaurus 2.2.0 and trying to test 'sidebar_custom_props', which is documented in Doc item metadata.

However, when I add sidebar_custom_props in page front matter as follows,

---
...
sidebar_custom_props:
  prop: test
---

The following error occurs in the parent page and sibling pages:

This page crashed.
Cannot read properties of undefined (reading 'toLowerCase')

The error occurs whether or not I try to access the props using useCurrentSidebarCategory().items and item.customProps. That is, simply adding sidebar_custom_props in page front matter seems to cause the error.

Is there any prerequisites for using sidebar_custom_props?

I'd greatly appreciate any help in solving this issue.

Never mind. We found out that the page crash is due to an internal issue on swizzled code that includes front matter manipulation.
