i18n: Getting ERROR 404 on Google search console

Version

v5.3.0

Steps to reproduce

['nuxt-i18n', {
      parsePages: false,
      locales: ['es'],
      strategy: 'prefix',
      detectBrowserLanguage: {
        useCookie: true,
        cookieKey: 'i18n_redirected',
        alwaysRedirect: true,
        fallbackLocale: 'es'
      },
      vueI18n: {
        messages: {
          'es': require('./locales/es.json')
        }
      }
    }],

Here is my nuxt-i18n configuration.

What is expected ?

Redirect to /es as it is the only one available language.

What is actually happening?

Google Search Console is telling me that I have an ERROR 404 in / when crawling data from my website

Additional comments?

I have no problem entering the webpage, but my website is not being indexed by Google on their Search Engine because of this.
