Thanks for reporting! I have been able to reproduce the issue.

Does you project have a tsconfig.json file? If so, you can add frontmatter support by adding the mdx → plugins section in it. For example, see our frontmatter fixture.

Configuration for remark plugins is new since version 1.2.0. I welcome any feedback on this.

Regardless of the above, this error should not pop-up. I will look into it soon.

yep we're using the Typescript starter for Docusaurus in this instance
