Astro站点用Vercel适配器部署Hybrid模式时静态页面404

已在Vercel上部署Astro站点并设置为Hybrid模式，构建过程无错误，但出现以下问题：

• 静态资源仅存在index.html，其他静态页面均无法正常访问
• 非静态页面可正常运行，但所有静态页面访问时都会返回Vercel的404错误，甚至自定义404页面也无法访问

Astro配置 #

import { defineConfig } from "astro/config";
import tailwind from "@astrojs/tailwind";
import svelte from "@astrojs/svelte";

import vercel from "@astrojs/vercel/serverless";

// https://astro.build/config
export default defineConfig({
  integrations: [tailwind(), svelte()],
  output: "hybrid",
  adapter: vercel(),
  vite: {
    optimizeDeps: {
      exclude: ["oslo"],
    },
  },
});

构建日志（显示预渲染路径正常） #
