error handling in fetch

Rufus Mathews 
function CheckError(response) {
  if (response.status >= 200 && response.status <= 299) {
    return response.json();
  } else {
    throw Error(response.statusText);
  }
}

// Now call the function inside fetch promise resolver
fetch(url)
  .then(CheckError)
  .then((jsonResponse) => {
  }).catch((error) => {
  });

                                    export async function getStaticProps(context) {
  const res = await fetch(`https://...`)
  const data = await res.json()

  //use this statement for the program not to crush but go back to the home page
  if (!data) {
    return {
      redirect: {
        destination: '/',
        permanent: false,
      },
    }
  }

  return {
    props: {}, // will be passed to the page component as props
  }
