Reproduction link

https://codesandbox.io/s/xenodochial-tree-xr79x?file=/pages/index.vue

Steps to reproduce

Just added the moduel using yarn add @nuxtjs/sitemap, this is my config.

Modules

modules: [
        // https://go.nuxtjs.dev/axios
        '@nuxtjs/axios',
        // https://go.nuxtjs.dev/pwa
        '@nuxtjs/pwa',
        // https://go.nuxtjs.dev/content
        '@nuxt/content',
        '@nuxtjs/dayjs',
        // keep this module at the end
        '@nuxtjs/sitemap',
    ],

Sitemap options

 sitemap: {
        // options
        hostname: process.env.main_base_URL,
        gzip: true,
        exclude: ['/secret', '/admin/**'],
        routes: [
            '/about',
            '/contact',
            {
                url: '/view/javascript-tips-tricks-n1',
                changefreq: 'daily',
                priority: 1,
                lastmodISO: '2017-06-30T13:30:00.000Z',
            },
        ],
    },

What is expected ?

Should generate a sitemap

What is actually happening?

instead an error pops up that says: [sitemap-module] The hostname option is mandatory in your config on spa or generate build mode

Fwiw I don't have this problem:

  sitemap: {
    hostname: process.env.SITEMAP_HOSTNAME,
  }

is working.

@BroJenuel as explained in the error message, the hostname value is mandatory in static target. But your main_base_URL is empty during the nuxt.config.jsscript execution because your Nuxt var envs are setted by that same file.

You have to use a constant as follows:

const main_base_URL =  'https://brojenuel-blog.ml';

export default {
   sitemap: {
        hostname: main_base_URL
    },
    env: {
        main_base_URL
    },
    ...
}

sitemap: {
        hostname: main_base_URL
    },
    env: {
        main_base_URL
    },

thanks it worked

this doesn't work for me.. was getting this error:
