Hi, for some reason when I run freshly built docker image, it throws on entering the page:

 ⨯ Error: Cannot find module './undefined.json'

Config:

const nextConfig = {
    reactStrictMode: true,
    staticPageGenerationTimeout: 180,
    i18n: {
        locales: ['en', 'pl'],
        defaultLocale: 'en',
        localeDetection: false,
    }
}

That's how I import locales in my pages:

export async function getStaticProps(context: GetStaticPropsContext) {
  const locale = context.locale || 'en'
  return {
    props: {
      messages: (await import(`../locales/${locale}.json`)).default
    }
  }
}

Error doesn't show up when I do next build & run locally. I thought locale files might be missing, but I went into container with bash exec and everything is in place, so no idea, maybe context has undefined params in docker for some reason.
