Describe the bug

If I turn off rehype-slug plugin, it still adds undefined link to headers.

content: {
    markdown: {
      rehypePlugins: {   
        "rehype-slug": false
      }
    }
  },

What I then get in html:

<a href="#undefined"><!--[-->My test header<!--]--></a>

If you just want to disable anchor link generation on headings, you can do so by setting anchorLinks option in the nuxt.config.ts to false.

But you also have a point, that it should automatically be disabled, if id is undefined.

Thank you, I haven't noticed this option. Now it works as expected with the anchorLinks turned off.

Should be fixed with https://github.com/nuxt/content/releases/tag/v2.5.0
