La til headeren connection: keep-alive

[tepose]

Vi får feilen:

FetchError: request to http://dp-rapportering/rapporteringsperiode/1842211755 failed, reason: socket hang up
    at ClientRequest.<anonymous> (/node_modules/@remix-run/web-fetch/src/fetch.js:112:11)
    at ClientRequest.emit (node:events:518:28)
    at emitErrorEvent (node:_http_client:103:11)
    at Socket.socketCloseListener (node:_http_client:479:7)
    at Socket.emit (node:events:530:35)
    at TCP.<anonymous> (node:net:343:12) {
  type: 'system',
  errno: 'ECONNRESET',
  code: 'ECONNRESET',
  erroredSysCall: undefined
}

som virker å være en feil med fetch. Det blir foreslått å sette headeren connection: keep-alive for å løse dette fra node <=19 (vi bruker 22.x).
