This is my code:

import City from '@/types/city'

export default async function CitiesList() {
  const cities = await (
    await fetch('http://localhost:8000/api/cities', {
      method: 'GET'
    })
  ).json()

  return (
    <>
      {cities.map((city: City) => (
        <>{city.name}</>
      ))}
    </>
  )
}

I get the response:

errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '::1',
  port: 8000

I am quite helpless... 😦
