typescript - 如何使用 TypeScript 中编码的 CloudFunction 将 admin.firestore.FieldValue.serverTimestamp() 传递给 update() 方法

Question

如何将 admin.firestore.FieldValue.serverTimestamp() 传递给 update() 方法？我想将其插入数组中，如下所示：

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp(functions.config().firebase);
exports.sendNote = functions.https.onCall(async(data,context)=>{
const numeroSender: string = data['numeroSender'];
const amisA = admin.firestore().collection('Amis').doc(numeroReceiver);
const connaissanceABBA:number = 3.0;
const version:number = 1;
const time = admin.firestore.FieldValue.serverTimestamp();
await amisA.update({
            [`amis.${numeroSender}`] : [time,connaissanceABBA,version]
        });
});

但我得到这个错误

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 value. FieldValue.serverTimestamp() cannot be used inside of 
an array (found in field `amis.+33651177261`.`0`).

您可以使用 admin.firestore.Timestamp.now() 而不是 admin.firestore.FieldValue.serverTimestamp()

const time = admin.firestore.Timestamp.now();
await amisA.update({
        [`amis.${numeroSender}`] : 
           {
    connaissanceABBA: connaissanceABBA,
    version: version,
    ts: firebase.firestore.FieldValue.serverTimestamp()
  }
});
});
