[Bug]: Statuscode from getPageData is not applied

[manuelJung]

Summary

export async function getServerData() {
  return {
    status: 404,
    props: {},
  }
}

when my getServerData fn on a ssr route returns a 404 status (or any other statuscode) netlify will always send a 200 statuscode since this is hardcoded (which can be seen here). when data.serverDataStatus yields a 404 or 500 we should return the getErrorResponse fn instead

Steps to reproduce

• create a gatsby project with an ssr route and add

export async function getServerData() {
  return {
    status: 404,
    props: {},
  }
}

• deploy it to netlify (or serve with netlify locally)
• call the ssr-route in the browser an see the statuscode send from netlify (it will be a 200)

! serving with gatsby (gatsby serve) wont work since here it works correctly)

I am afraid this issue is causing me some trouble as well. A fix would be highly appreciated.
