ORIGINAL EXCEPTION: No provider for Auth! : Ionic Cloud Services - authentication

Question

I set up Ionic Cloud Service and went through the initial process of authorizing a user.
import {Component} from '#angular/core';
import {NavController} from 'ionic-angular';
import {Auth, User, UserDetails, IDetailedError} from '#ionic/cloud-angular';
#Component({
templateUrl: 'build/pages/signup/signup.html'
})
export class SignupPage {
constructor(public auth: Auth, public user: User){
let details: UserDetails = {'email': 'hi#ionic.io', 'password': 'puppies123'};
this.auth.signup(details).then(() => {
// `this.user` is now registered
}, (err: IDetailedError<string[]>) => {
for (let e of err.details) {
if (e === 'conflict_email') {
alert('Email already exists.');
} else {
// handle other errors
}
}
});
}
}
For some reason I am getting this error:ORIGINAL EXCEPTION: No provider for Auth!
ORIGINAL STACKTRACE:
Error: DI Exception
Everything is setup to a tee like the ionic cloud docs suggest : https://docs.ionic.io/services/auth/#setup
I've looked everywhere for this answer

Answer 1

In the setup instructions it talks about how to add the ionic cloud NgModule to your module's imports:
https://docs.ionic.io/setup.html
import { CloudSettings, CloudModule } from '#ionic/cloud-angular';
const cloudSettings: CloudSettings = {
'core': {
'app_id': 'APP_ID'
}
};
#NgModule({
declarations: [ ... ],
imports: [
IonicModule.forRoot(MyApp),
CloudModule.forRoot(cloudSettings)
],
bootstrap: [IonicApp],
entryComponents: [ ... ],
providers: [ ... ]
})
export class AppModule {}
I had missed these steps. Making this change fixed the problem.

Answer 2

Try this
#Component({
templateUrl: 'build/pages/signup/signup.html',
providers: [Auth]
})
Not sure if it works because the ionic docs don't say anything about this, but it seems logical looking at your Error

Answer 3

Passing Auth in providers, starts to show that error in console:
Cannot read property 'config' of undefined
