Nuxt Pages not getting crawled

I have made a website using NUXT that needs SEO

When I use www.XML-sitemaps.com website to see if it can find all my pages, it only finds the home page and none of the other routes.

My robots.txt file looks like this:

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

I am using @nuxtjs/sitemap to generate the sitemap.xml.

my nuxt.config.js looks like:

export default {
  // Target: https://go.nuxtjs.dev/config-target
  target: 'static',

  // Global page headers: https://go.nuxtjs.dev/config-head
  head: {
    title: 'talk-to-target,
    meta: [
      { charset: 'utf-8' },
      { name: 'viewport', content: 'width=device-width, initial-scale=1' },
      { hid: 'description', name: 'description', content: '' },
      { name: 'format-detection', content: 'telephone=no' }
    ],
    link: [
      { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
    ]
  },

  // Global CSS: https://go.nuxtjs.dev/config-css
  css: [
    '~/assets/CSS/app.scss'
  ],

  // Plugins to run before rendering page: https://go.nuxtjs.dev/config-plugins
  plugins: [
  ],

  // Auto import components: https://go.nuxtjs.dev/config-components
  components: true,

  // Modules for dev and build (recommended): https://go.nuxtjs.dev/config-modules
  buildModules: [
    // https://go.nuxtjs.dev/typescript
    '@nuxt/typescript-build',
    // https://go.nuxtjs.dev/stylelint
    '@nuxtjs/stylelint-module'
  ],

  // Modules: https://go.nuxtjs.dev/config-modules
  modules: [
    'bootstrap-vue/nuxt',
    '@nuxtjs/axios',
    '@nuxtjs/pwa',
    'nuxt-lazy-load',
    '@nuxtjs/robots',
    '@nuxtjs/sitemap'
  ],
  robots: {
    UserAgent: '*',
    Disallow: ''
  },
  sitemap: {
    generate: true,
    hostname: 'https://talktotarget.beter.in/',
    gzip: true
  },

  // Axios module configuration: https://go.nuxtjs.dev/config-axios
  axios: {
    baseURL: '/'
  },

  // PWA module configuration: https://go.nuxtjs.dev/pwa
  pwa: {
    manifest: {
      lang: 'en'
    }
  },

  // Build Configuration: https://go.nuxtjs.dev/config-build
  build: {
    standalone: true
  }
}

Result on xml-sitemaps:

nuxt-community / sitemap-module
