So I have this function that gets some numbers from another function

Now I am using typescript and NextJS 14

Problem is, how do I access the overallMatches.matches object?

The route /api/last10/matches returns a json from prisma

export const getPlayerPerformance = cache(async (player_id: string, surface: string) => {
    const time_0 = performance.now();

    // const overallMatches = await cachedLatestMatches(player_id, surface)
    const overallMatches = await fetch(`/api/last10/matches?id=${player_id}&surface=${surface}`, {method: "GET"})

    console.log("matches:", overallMatches.matches.length)

    const time_1 = performance.now();
    console.log(player_id, surface, "Time to fetch matches: ", time_1 - time_0, "ms");

    const [overall_perf] = await Promise.all([
        getPerformance(overallMatches.matches.slice(0, 10), player_id),
    ]);

    return {
        perf_surface: overall_perf.perf_surface,
    };
});
