I create a firebase function to return posts collection, for some reason cloud function return only one post(document). But when I run this function locally, in terminal I get all posts. Any idea why?



const functions = require('firebase-functions');
const admin = require('firebase-admin');
const cors = require('cors')({origin: true});
admin.initializeApp();

exports.postWidget = functions.https.onRequest((request, response) => {
cors(request, response, () => {});

var db = admin.firestore();

var postsRef = db.collection('posts')
postsRef.where('postStatus', '==', 'published').get()
.then(snapshot => {
snapshot.forEach(doc => {
let data = doc.data()
return response.send(data)
});
})
.catch(err => {
console.log('Error getting documents', err);
});

});

          You're calling response.send(data) multiple times in forEach loop. That's not likely to do what you want, as you're only supposed to call send() once with then entire response. Instead, you should be collecting all the data to send in a single object, and call send() with that one object.
