Invalid i18n config

Why This Error Occurred​

In your next.config.js file, you provided an invalid config for the i18n field. This could mean the limit for 100 locale items was exceeded.

Possible Ways to Fix It​

Make sure your i18n field follows the allowed config shape, limits, and values:

module.exports = {
  i18n: {
    // These are all the locales you want to support in
    // your application
    locales: ['en-US', 'es', 'fr', 'nl-NL'],
    // This is the default locale you want to be used when visiting
    // a non-locale prefixed path e.g. `/hello`
    defaultLocale: 'en-US',
    // This is a list of locale domains and the default locale they
    // should handle (these are only required when setting up domain routing)
    domains: [
      {
        domain: 'example.com',
        defaultLocale: 'en-US',
        // other locales that should be handled on this domain
        locales: ['es'],
      },
      {
        domain: 'example.nl',
        defaultLocale: 'nl-NL',
      },
      {
        domain: 'example.fr',
        defaultLocale: 'fr',
      },
    ],
  },
}
