upgrade to angularFire 7.0.3 and 4 new error

[LanderBeeuwsaert]

An error after upgrading firebase & angularFire (still using the compat library :)):
Any idea?

**Angular: 12.2.0

**Firebase: 9.0.1

**AngularFire: 7.0.3 and 7.0.4

Other (e.g. Ionic/Cordova, Node, browser, operating system):
node 14
windows 10
chrome

How to reproduce these conditions

Failing test unit, Stackblitz demonstrating the problem

error when looking in chrome devtools:
Emulator URL must start with a valid scheme (http:// or https://). (auth/invalid-emulator-scheme).

code in app module:

This issue does not seem to follow the issue template. Make sure you provide all the required information.

The format has changed.
['localhost', 9099] becomes ['http://localhost:9099']

@tja4472 is correct. In 7.0 we broke the USE_EMULATOR token for auth, instead taking it in a form that the JS SDK expects now that we have a typescript version that allows Parameters<>; rather than smoothing over this API inconsistency.

This seems trivial and annoying but means we no longer have to take feature requests and cut minor releases when the auth SDK adds new options to the useEmulator function.

@tja4472 Can you take a look at #2932?

just for reference, changing as suggested solved the issue

Second, confirm. Docs should be updated. I can make a PR if you'll like.

I had to use the following in my app.module:

{ provide: USE_FIRESTORE_EMULATOR, useValue: environment.useEmulators ? ['127.0.0.1', 8080] : undefined },
