how to set server time stamp with firestore admin nodejs sdk?
const firebase = require('@firebase/app').default;
require('@firebase/firestore')
const admin = require('firebase-admin')
const functions = require('firebase-functions')
// initialize the admin SDK...
exports.setUpdatedDate = functions.firestore.document('/foos/{fooId}/bars/{barId}')
.onCreate(event => {
admin.firestore().collection('foos').doc( event.params.fooId )
.set({
updatedDate: firebase.firestore.FieldValue.serverTimestamp()
}, {merge:true})
})
运行 上面的函数 shell 我得到:
Cannot encode type ([object Object]) to a Firestore Value
at Function.encodeValue (...\functions\node_modules\@google-cloud\firestore\src\document.js:772:11
