Firebase数据库onCreate不更新所有记录

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

exports.updateAllRecords = functions.database.ref('/path/to/records/{recordId}')
    .onCreate((snapshot, context) => {
        const newValue = snapshot.val();
        const updates = {};

        // 遍历所有记录并进行更新操作
        return admin.database().ref('/path/to/records').once('value')
            .then((snapshot) => {
                snapshot.forEach((childSnapshot) => {
                    const childKey = childSnapshot.key;
                    updates['/path/to/records/' + childKey] = newValue;
                });

                // 执行批量更新操作
                return admin.database().ref().update(updates);
            });
    });
