Weird problem with a ...__data.json?x-sveltekit-invalidated=001 involved

[205g0]

I ha;ve...

// 1 All movies page
/movies/+page.svelte // and +page.server.ts, etc.

// 2 Detail movie page
/movies/[id]/+page.svelte // and +page.server.ts, etc

When I load 2 intro the browser, 2 loads and after loaded, /movies/__data.json?x-sveltekit-invalidated=001 is requested in Inspector's Network tab (as said after 2 being loaded).

I removed any connection and link between 1 and 2 but nothing changed.
