javascript - Firebase 云函数超时

Question

以下函数在用 shell 测试时运行良好，数据是在 firestore 中创建的。 当推送到产品中时，它返回 Function execution take 60002 ms, finished with status: 'timeout'

有什么意见吗？

exports.synchronizeAzavista = functions.auth.user().onCreate(event => {

    console.log('New User Created');

    const user = event.data;
    const email = user.email;
    const uid = user.uid;

    return admin.database().ref(`/delegates`)
        .orderByChild(`email`)
        .equalTo(email)
        .once("child_added").then(snap => {
            const fbUserRef = snap.key;

            return admin.firestore().collection(`/users`).doc(`${fbUserRef}`).set({
                email: email,
                uid: uid
            }).then(() => console.log("User Created"));
        });
});

编辑

我已经用以下内容更新了我的代码，但我仍然得到 Function returned undefined, expected Promise or value 但我无法确定我的函数在哪里返回未定义。为什么我的 getUser() 函数没有返回任何内容？

const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.synchronizeAzavista = functions.auth.user().onCreate(event => {

    console.log('New User Created');//This log

    const user = event.data;
    const email = user.email;
    const uid = user.uid;

    console.log('Const are set');//This log

    getUser(email).then(snap => {

        console.log("User Key is " + snap.key);//No log

        const fbUserRef = snap.key;

        return admin.firestore().collection(`/users`).doc(`${fbUserRef}`).set({
            email: email,
            uid: uid
        });
    }).then(() => console.log("User Data transferred in Firestore"));
});

function getUser(email) {

    console.log("Start GetUser for " + email);//This log 

    const snapKey = admin.database().ref(`/delegates`).orderByChild(`email`).equalTo(email).once("child_added").then(snap => {
        console.log(snap.key);//No Log here
return snap;
    });
    return snapKey;
}

您不会通过写入 Firestore 来返回 promise 。

exports.synchronizeAzavista = functions.auth.user().onCreate(event => {
    const user = event.data;
    const email = user.email;
    const uid = user.uid;

    return admin.database().ref(`/delegates`)
        .orderByChild(`email`)
        .equalTo(email)
        .once("child_added").then(snap => {
            const fbUserRef = snap.key;

            return admin.firestore().collection(`/users`).doc(`${fbUserRef}`).set({
                email: email,
                uid: uid
            });
        });
});
