I want to access a subcollection called 'followers' from a given id under the 'mobile\_user', this contains the id's of the followers. I want to loop through each of the id's in the followers subcollection and query data from the 'mobile\_user' collection . Notice that the id in the 'followers' subollection is the id of another user under 'mobile\_user' which contains the document data i want.

I've tried messing around with promises with no luck, i'm able to do the foreach loop and just query the name as a test but the array gets populated correctly but the populated array with the names of the N users are never returned. 

I need some assistance with my code, promises are driving me nuts I can't get the hang around them.

```
const getFollowers = (data, context) => {
        return new Promise((resolve, reject) => {

            let id = data.id
            const mobileUserRef = db.collection('mobile_user')

            return mobileUserRef.doc(id).collection('followers')
                .get()
                .then(function (doc) {
                    var result = []
                    doc.forEach(function (follower) {
                        mobileUserRef.doc(follower.id).get()
                            .then(function (followerdoc) {
                                result.push({
                                    name: followerdoc.data().name,
                                })
                                console.log(result)
                            })
                    })
                    return Promise.all(result);
                })
        });
    }

```

The expected result is an array with the data of every id under the followers sub, like this: 

In this example only 2 user id's are present

```
[ { name: 'Luis' }, { name: 'Marb Rocha' } ]

```
