site: error while rendering error page

[teemingc]

Houston, we have a problem

Some thoughts on this issue sveltejs/kit#10565 (comment)
The main cause is a rendering error in the root +layout.svelte while rendering the default error page.

svelte/sites/svelte.dev/src/routes/+layout.svelte

Line 27 in 28d6b34

{#if !$page.route.id.startsWith('/blog/')}

TypeError: Cannot read properties of null (reading 'startsWith')

but the error message being incorrect is a sveltekit issue
