Undefined frontmatter on page navigation

[bryanmylee]

When navigating to any page within the documentation, the following error is thrown:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'frontmatter')
    at kitDocs.js:7
    at sync (index.mjs:77)
    at Array.<anonymous> (index.mjs:89)
    at Object.set (index.mjs:34)
    at KitDocs.svelte? [sm]:6
    at run (index.mjs:18)
    at Array.forEach (<anonymous>)
    at run_all (index.mjs:24)
    at destroy_component (index.mjs:1833)
    at Object.destroy [as d] (__layout-kit-docs.svelte? [sm]:46)

It seems to be coming from this line in kitDocs.js:

export const frontmatter = derived(kitDocs, ($kitDocs) => $kitDocs?.meta.frontmatter);

Seems to have resolved itself after restarting the dev server.
