我根據(jù)此處的教程編寫了一個 firebase Http 可調用云函數(shù)：https : //www.youtube.com/watch?v= 3hj_r_N0qMs from the firebase team。但是，我的函數(shù)無法驗證用戶（我）的自定義聲明，因為“context.auth”未定義我已將 firebase、firebase 工具、firebase-functions 和 admin SDK 更新到最新版本。我的函數(shù)/Index.ts 文件import * as functions from 'firebase-functions';import * as admin from 'firebase-admin';admin.initializeApp()export const addAdmin = functions.https.onCall((data, context) => {    if (context.auth.token.admin !== true) {        return {            error: 'Request not authorized'        };    }    const uid = data.uid    return grantAdminRole(uid).then(() => {        return {            result: `Request fulfilled!`        }    })})async function grantAdminRole(uid: string): Promise<void> {    const user = await admin.auth().getUser(uid);    if (user.customClaims && (user.customClaims as any).admin === true) {        console.log('already admin')        return;    }    return admin.auth().setCustomUserClaims(user.uid, {        admin: true,    }).then(() => {        console.log('made admin');    })}我的 app.component.ts 代碼makeAdmin() {    var addAdmin = firebase.functions().httpsCallable('addAdmin');    addAdmin({ uid: '[MY-USER-ID]' }).then(res => {      console.log(res);    })    .catch(error => {      console.log(error)    })  }如果我不嘗試訪問“上下文”并且我可以向該用戶添加自定義聲明，則該函數(shù)執(zhí)行良好。但是，如果我嘗試訪問 context.auth，則會發(fā)現(xiàn)錯誤：Unhandled error TypeError: Cannot read property 'token' of undefined"
