Describe the bug

Original error stack trace: TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type boolean (false)

at Template._write (/node_modules/@11ty/eleventy/src/Template.js:751:34)

Reproduction steps

Use JS frontmatter as follows

---js
{
layout: "layouts/default.njk",
pagination: {
alias: "spage",
data: "pages",
size: 1,
addAllPagesToCollections: true,
},
eleventyComputed: {
title: (data) => data.spage.title,
eleventyNavigation: {
  key: (data) => {
    if (data.spage.navigation) {
      return data.spage.navigation.key;
    }

    return null;
  },
  parent: (data) => {
    if (data.spage.navigation && data.spage.navigation.parent) {
      return data.spage.navigation.parent.navigation.key;
    }

    return null;
  }
},
permalink: (data) => {
  if (data.spage.slug) {
    return `${data.spage.slug.current}index.html`;
  }

  return false;
}
}
}
---

Expected behavior

To build pages that have a slug, and to ignore ones with a false permalink

is this still relevant or was it fixed with https://github.com/11ty/eleventy/issues/2853

I believe this is still an issue. But I've worked around it. I think it happens when JS is used in the front matter for a permalink.

I'm running into this with Eleventy 2.0.1 with no serverless functionality in play: using pagination to iterate over an array in the global data, then a 'permalink' function in eleventyComputed.js, everything works fine unless I return FALSE to suppress output for one of the items.

Happy to whip up a bite-sized script to duplicate it if it helps, but it does seem to mirror just what this issue describes. Curious what your workaround was, @ryangittings?
