Svelte redirect to Microsoft Entra ID fails due to CORS

I am building a Svelte application, where the user must login using Microsoft Entra ID.I have made a hooks.server.ts file, which checks all traffic for a access token.If access token is not present the user must redirect to Microsoft for authentication.

This works fine when I redirect to page with page.server.ts file, then I am allowed to redirect to Microsoft.

However, it fails because of CORS in the case that client-side svelte (+page.svelte) makes a GET request to the server-side (+server.ts). Here the hooks.server.ts will notice the token is expired and try and redirect the user to Microsoft Entra ID, but it fails now because of CORS.

enter image description here

The application uses SvelteKit to navigate between pages and handle client, server-side logic.I use redirect to navigate from hooks.server.js to Microsoft Entra ID.

import { redirect, type Handle } from '@sveltejs/kit';

I want to always be able to redirect to Microsoft Entra ID for access and id token.
