This solution works for me:

const {Timestamp} = require("firebase-admin/firestore")

{
  todo:input,
  timestamp: Timestamp.now(),
}

For those who are using the Admin SDK with NodeJS:

import { FieldValue } from '@google-cloud/firestore'

const docData = {
  userName: 'Lucas'
  createdAt: FieldValue.serverTimestamp()
}

You could find all the external API's references here: https://firebase.google.com/docs/reference/admin/node/firebase-admin.firestore

You can try:

import { serverTimestamp } from '@firebase/firestore'

timestamp: serverTimestamp()

I hope it'll work

Make sure to import firebase from 'firebase' and not import firebase from './firebase'.

Had the same problem than you, fixed it by doing this.

Make sure you have correct timestamp value, or don't pass timestamps if you don't need them. Try passing this json to todos collection:

{
  todo:input,
  timestamp: firebase.firestore.FieldValue.serverTimestamp() || null
}

Make sure you have FieldValue inside firebase.firestore by logging console.log(firebase.firestore) and try console.log(Object.keys(firebase.firestore))
