当我打开主页jadi-domashno-alexohlin.vercel.app并点击导航栏中的链接“Ме ни”时，没有问题，但如果我直接导航到该页面，或者如果我只是刷新它jadi-domashno-alexohlin.vercel.app/meni，它会显示空白页面。我的代码在这里gitlab.com/alexohlin/jadi-domashno

这是我的app/meni/page.tsx代码

import { GotvacInterface } from "Types/types";
import MeniPage from "components/MeniPage";
import { Metadata } from "next";

export interface userPointInterface {
  lat: number;
  lng: number;
}

export const metadata: Metadata = {
  title: "Мени - „Јади Домашно“",
  description: "Погледнете го менито на платформата „Јади Домашно“",
  openGraph: {
    title: "Мени - „Јади Домашно“",
    description: "Погледнете го менито на платформата „Јади Домашно“",
    url: "https://jadi-domashno-alexohlin.vercel.app/meni",
  },
  twitter: {
    title: "Мени - „Јади Домашно“",
    description: "Погледнете го менито на платформата „Јади Домашно“",
  },
  appleWebApp: {
    title: "Мени - „Јади Домашно“",
  },
};

const fetchGotvaci = async () => {
  const gotvaciRes = await fetch(
    "https://band-frosted-brake.glitch.me/gotvaci?_embed=jadenja"
  );
  return gotvaciRes.json();
};

export default async function Meni() {
  const gotvaci: GotvacInterface[] = await fetchGotvaci();
  
  return <MeniPage gotvaci={gotvaci} />;
}

这是我在Meni页面中导入的MeniPage组件：
