Firebase 身份验证花费太长时间在云中创建用户 function

Question

currently I'm having a problem where calling the auth#createUser method takes up to 10 seconds to proceed to call it's Promise#then method. I'm getting these timestamps from the firebase & google cloud function logger. I feel that I may be doing something wrong, although I can't figure out what I am doing wrong. Before you say to contact the firebase support, I already have and they told me to come here.

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

let database = admin.firestore();

exports.createUser = functions.https.onCall((data, response) => {
    console.log(data);
    console.log(response);

    admin.auth().createUser({
        email: data.email,
        emailVerified: false,
        password: data.password,
        displayName: data.name,
        disabled: false,
    }).then(user => {
        database.collection('users').doc(data.username).set({
            uid: user.uid,
            email: data.email,
            name: data.name,
            username: data.username
        }).catch(error => {
            throw new functions.https.HttpsError(error)
        });
        console.log('The entire thing is done successfully!');
        return {
            response: user
        }
    }).catch(error => {
        throw new functions.https.HttpsError(error);
    });
    console.log('Found my way to the end of the method');
});

You're not dealing with promises correctly. onCall functions should return a promise that resolves with the data that you want to return to the client. Right now, your function is returning nothing. The return statement inside the then callback isn't actually sending anything to the client. What you will need to do instead is return the promise chain:

return admin.auth().createUser(...).then(...).catch(...)

Note the return in front of all that.

Also, you will need to handle the promise returned by set() . Just calling catch isn't sufficient. You will need to return that promise as well from the then callback.

I strongly suggest learning how promises work in JavaScript - without proper handling, your functions will simply not work correct, and often behave in confusing ways.
