ssrでfetchしてるときにあえてsetTimeout使って遅らせたいときの、setTimeoutの書き方

promise_settimeout.js

return new fetch(`/hogehoge`)
.then(response => {
  return response.json().then(json => ({ status: response.status, json }))
})
.then(r => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      console.log("settimeout finish")
      resolve(0)
      return dispatch({ type: "FINISH" })
    }, 5000)
  })
})
