BUG: Timestamp.toObject() returning zeroed value

In the latest version, 3.21.4, the Timestamp.toObject() function isn't working correctly.

Previously it would return the timestamp as an object with keys for seconds and milliseconds. However now it is returning zero values for both.

This is a function where I noticed the issue, I've added some logging which pointed out toObject() as being the problem.

function dateToTs(date: Date): Timestamp {
  const ts = new Timestamp();
  ts.fromDate(date);
  console.log(
    "date:",
    date,
    "timestamp:",
    ts.getSeconds(),
    ts.getNanos(),
    ts.toObject(),
  );
  return ts;
}

See the screenshot below for the resulting console log, where you can see the seconds and milliseconds are set, but the toObject return is zeroed

Parti da Timestamp.toObject() e confronta il risultato con getSeconds() e getNanos() quando il valore viene creato tramite fromDate(), utilizzando l’esempio dateToTs() del report. Riproduci i campi azzerati nella versione 3.21.4; il lavoro è completato quando toObject() restituisce i valori valorizzati di secondi e millisecondi.
