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',
      },
    ],
  },
}
