I'm fairly new to Firebase and Node.js. I have created this function in my Cloud Functions to login users with a custom token:
const functions = require('firebase-functions'); const admin = require('firebase-admin'); var serviceAccount = require("./service-account.json"); admin.initializeApp({ credential: admin.credential.cert(serviceAccount), databaseURL: functions.config().firebase.databaseURL }); const cors = require('cors')({origin: true}); exports.login = functions.https.onRequest((req, res) => { cors(req, res, () => { //doing some validation.. //get password from db and match it with input password var userRef = admin.firestore().collection('users') userRef.where('username', '==', username).get() .then(snapshot => { if(snapshot.size > 1){ res.status(200).send("Invalid account!"); return; } snapshot.forEach(doc => { var userPass = doc.data().password; //if password matches, generate token, save it in db and send it if(userPass && password == userPass){ var uid = doc.data().uid; var admin = Boolean(doc.data().admin); var server = Boolean(doc.data().server); var additionalClaims = { admin: admin, server: server }; admin.auth().createCustomToken(uid, additionalClaims) .then(function(customToken) { res.status(200).send("token:" + customToken); }) .catch(function(error) { res.status(200).send("Token creation failed!"); }); //save token in db.. }else{ res.status(200).send("Invalid credentials!"); } }); }) .catch(err => { res.status(200).send("User authentication failed!"); }); }); }); I used the token generation method in the documentation, but whenever I try to login a user it throws the error:
TypeError: admin.auth is not a function at snapshot.forEach.doc (/user_code/index.js:128:27) at QuerySnapshot.forEach (/user_code/node_modules/firebase-admin/node_modules/@google-cloud/firestore/src/reference.js:1012:16) at userRef.where.get.then.snapshot (/user_code/index.js:110:13) at process._tickDomainCallback (internal/process/next_tick.js:135:7) What could it be that I'm doing wrong?
