[Firestore] New documents with a persisted ID still creates a new ID

[jdjuan]

1. Version info

Angular: 5.2.0

Firebase: 4.12.0

AngularFire: 5.0.0-rc.6

Node: 8.9.3

Other (e.g. Ionic/Cordova, Node, browser, operating system): Windows 10

2. How to reproduce these conditions

Find all the source code and credentials to a sanitized Firestore project here: StackBlitz

2.1 Steps to set up and reproduce

1. Create a new Firestore project and bind to an Angular App
2. Create a reference to a new collection and try to add a persisted ID as specified in the documentation:

const id = this.afs.createId();
const item: Item = { id, name };
this.itemsCollection.add(item);

2.2 Actual Behavior

2.3 Expected behavior

Credentials are available in the StackBlitz project

2.4 Solution

The desired behavior can be achieved like this. So either there's a real issue, or the docs are outdated 🤔

const id = db.createId();
const user = { name:'juan' };
users.doc(id).set({ name: 'juan' });
