TypeError: Cannot read properties of undefined (reading 'type')

I'm getting the following error when trying to run the marked-it-cli command (it uses the --keyref-file option only), and I'm not sure how to solve it.

Hi, the problem needs to be reproducible locally. Can you give either a pointer or an attachment of the source markdown file that causes this problem? If you're not sure which file is causing it then you can run marked-it-cli with switch --verbose to make it log each file as it's read and written.

This can be reproduced in the original markdown-it-attrs dependency with the following content:

{: a} [b](c)

I've tried this case with the latest markdown-it and markdown-it-attrs releases and it no longer fails. So need to either move up to newer releases of these packages or determine if the fix for this case can be back-ported to our fork of markdown-it-attrs.
