Return data from load function while also redirecting the user?

[m1212e]

I do this in my layout to redirect the user to my oidc issuer if necessary:

import { codeVerifierCookieName, startSignin } from '$lib/auth/oidc';
import { redirect } from '@sveltejs/kit';
import type { LayoutServerLoad } from './$types';

export const load: LayoutServerLoad = async ({ url, cookies }) => {
	const { encrypted_verifier, recidret_uri } = startSignin({
		visitedUrl: url.toString()
	});

	cookies.set(codeVerifierCookieName, encrypted_verifier, {
		sameSite: 'strict',
		maxAge: 60 * 5,
		path: '/'
	});

	redirect(302, recidret_uri);
};

the, after they return from the login page, I want to do two things: First, I want them to be ridirected to where they initially visited. For this I have the state variable, which contains the originally visited URL. Second, I want to pass the credentials to the frontend. This is non working code since the redirect throws:

import type { PageServerLoad } from './$types';
import { codeVerifierCookieName, resolveSignin } from '$lib/auth/oidc';
import { error, redirect } from '@sveltejs/kit';

export const load: PageServerLoad = async ({ url, cookies }) => {
	const verifier = cookies.get(codeVerifierCookieName);
	if (!verifier) error(400, 'No code verifier cookie found.');

	const { state, tokenSet } = await resolveSignin(url.toString(), verifier);
	redirect(302, state.visitedUrl);
	return {
		tokenSet
	};
};

Is there an elegant way to achieve this? Thanks!
