page data disappears on page reload after upgrade from 2.37.0 to 2.37.1 #14390
Description
Describe the bug
when upgrading my SvelteKit project from 2.37.0 to 2.37.1. data loaded via load function in +page.server.ts is only loaded initially. if do a page refresh via the browser (hard or soft reload does not matter) the data is not available anymore and the page shows the loading spinner.
pages which are affected use the pattern below and stop working with version 2.37.1.
Reproduction
+layout.server.ts
import { type RequestEvent } from '@sveltejs/kit';
import * as model from '$lib/server/models';
import { getLocaleFromCookies, getLocaleFromHeaders, getSupportedLocale } from '$lib/i18n';
import type { LayoutServerLoad } from './$types';
export const load: LayoutServerLoad = async ({ locals, request, cookies }: RequestEvent) => {
const user = locals.user;
const chosenLocale = getLocaleFromCookies(cookies);
const acceptedLanguage = getLocaleFromHeaders(request.headers);
if (user && chosenLocale && chosenLocale !== user.language) {
model.user.update(user.id, { language: chosenLocale });
}
const locale = getSupportedLocale(chosenLocale || acceptedLanguage);
return {
locale,
user: locals.user,
acceptedLanguage,
chosenLocale,
};
};
+page.server.ts
export const load: PageServerLoad = async ({ params, locals }) => {
return {
ressources
};
}
+page.svelte
{#await data.ressources}
<Spinner />
</div>
{:then ressources}
{#each ressources as ressource, index (index)}
{@render card(ressource)}
{/each}
{/await}
