firebase-admin SDK Timestamps no longer compatible with fireorm collection-update method about fireorm HOT 1 OPEN

import * as admin from 'firebase-admin';
item.date = new admin.firestore.Timestamp(timestampData);
await admin.firestore().collection('test').doc(test.id).update({ item: item });

import * as admin from 'firebase-admin';
const { Timestamp } = require('@google-cloud/firestore'); // Had to change here because previous one was making error
item.date = new Timestamp(timestampData);
await admin.firestore().collection('test').doc(test.id).update({ item: item });

Error: Update() requires either a single JavaScript object or an alternating list of field/value pairs that can be followed by an optional precondition. Value for argument "dataOrField" is not a valid Firestore document. Detected an object of type "Timestamp" that doesn't match the expected instance (found in field "item.date"). Please ensure that the Firestore types you are using are from the same NPM package.)
