Nuxt3使用@nuxtjs/robots模块访问robot.txt遇404错误求助

我当前正在使用Nuxt3，访问robots.txt时出现404错误，使用的是robots模块。

我的nuxt.config.ts配置如下：

export default defineNuxtConfig({
    imports: {
        autoImport: true
    },

    modules: [
        '@unocss/nuxt',
        '@nuxtjs/robots',
    ],

    robots: {
        UserAgent: '*',
        Disallow: ''
    }
})

之后我执行了package.json中的generate和preview脚本，我的package.json内容如下：

{
  "private": true,
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "devDependencies": {
    "@iconify/json": "^2.1.112",
    "@unocss/nuxt": "^0.45.22",
    "nuxt": "3.0.0-rc.11"
  },
  "dependencies": {
    "@nuxtjs/robots": "^2.5.0"
  }
}

执行preview命令后，终端显示INFO: Accepting connections at http://localhost:3000.，应用能正常访问，但访问http://localhost:3000/robots.txt时会跳转到404页面。
