我有以下功能：
@H_404_2@const functions = require('firebase-functions');
const admin = require('firebase-admin');
const FieldValue = require('firebase-admin').FieldValue;
module.exports = functions.firestore
.document('students/{studentId}')
.onDelete(event => {
const student = event.data.prevIoUs.data();
const { id,semester } = student;
const classId = student.class;
const deleteObj = {};
deleteObj[id] = FieldValue.delete(); //Line 12,this is where the error orccurs
return admin
.firestore()
.collection('semesters')
.doc(semester)
.collection('students')
.doc(classId)
.update(deleteObj);
});
每次运行它我都会收到以下错误：
@H_404_2@TypeError: Cannot read property 'delete' of undefined at module.exports.functions.firestore.document.onDelete.event (/user_code/deleteStudent.js:12:37)看着docs我真的不知道我做错了什么？
@H_404_2@// Get the `FieldValue` object var FieldValue = require("firebase-admin").FieldValue; // Create a document reference var cityRef = db.collection('cities').doc('BJ'); // Remove the 'capital' field from the document var removeCapital = cityRef.update({ capital: FieldValue.delete() });更新
因此,使用Web等效工具似乎有效：admin.firestore.FieldValue.delete().但这似乎是一个bug,因为我在nodejs环境中？任何Firebaser都可以确认或拒绝这种情况吗？我很乐意提交错误报告.
