Javascript AstroJS混合模式服务器终结点返回404

我有一个AstroJS项目，这是我的astro.config.mjs:

import tailwind from "@astrojs/tailwind";
import vue from '@astrojs/vue';
import sanity from "@sanity/astro";
import { defineConfig } from 'astro/config';
import { sanityClientConfigWithCdn } from './const';
import node from '@astrojs/node';

export default defineConfig({
  output: 'hybrid',
  adapter: node({
    mode: 'standalone',
  }),
  integrations: [
    tailwind(), 
    sanity(sanityClientConfigWithCdn), 
    vue({appEntrypoint: "/src/vue.ts"}),
  ]
});

下面是我的测试API终结点:

import type { APIRoute } from "astro";

export const prerender = false;

export const GET: APIRoute = async ({ params, request }) => {
  return new Response(JSON.stringify({
    message: "TEST"
  }))
}

最后是我的页面文件 struct :

├── api
│   └── test.ts
└── [...lang]
    ├── index.astro
    └── news.astro

我收到此错误/警告:

06:49:15 PM [getStaticPaths] A `getStaticPaths()` route pattern was matched, but no matching static path was found for requested path `/404`.

Possible dynamic routes being matched: src/pages/[...lang]/index.astro.
06:49:15 PM [serve]    404                                     /404

起初我认为[...lang]动态路由是问题所在.但是，我仍然得到404即使删除整个目录.我正在执行npm run dev并try 访问http://localhost:3000/api/test(这是正确的主机和端口).有什么问题吗？
