Angularfire: getDownloadURL()

[WB3Tech]

I have a function which uploads an image to Firebase Storage. The code snippet (My Code) is the implementation; I made sure to reference the guidance here.

I played around to see if I could better understand the issue. I moved the following code outside of the '.pipe()' (My Test Code) and received an error that 'Object(...) is not a function'.
finalize(() => this.downloadUrl = ref.getDownloadURL() )
Thinking that it is the ref.getDownloadURL(), I just commented it out completely, and the error disappeared. Any idea what the issue may be?

My packges:
Angular: "@angular/core": "^5.0.0",
Firebase: "firebase": "^5.0.4",
AngularFire: "angularfire2": "^5.0.0-rc.10",
"rxjs": "^5.5.2",

My Code:
````
import {AngularFireStorage} from 'angularfire2/storage';
import {finalize} from 'rxjs/operators';

export class Component {

constructor( private fileStore: AngularFireStorage) { }

uploadPercent: Observable;
downloadUrl: Observable;

uploadHeaderImage(file: File) {

const _fileName = uuid();
const _filePath = '/event/' + _fileName;

const ref = this.fileStore.ref(_filePath);
const task = this.fileStore.upload(_filePath, file);

this.uploadPercent = task.percentageChanges();
task.snapshotChanges().pipe(
  finalize(() => this.downloadUrl = ref.getDownloadURL() )
).subscribe();

}

}

````
The Error:

ERROR Error: Uncaught (in promise): UnsubscriptionError: 1 errors occurred during unsubscription: 1) TypeError: Object(...) is not a function UnsubscriptionError: 1 errors occurred during unsubscription: 1) TypeError: Object(...) is not a function at new UnsubscriptionError (UnsubscriptionError.js:18) at SafeSubscriber.Subscription.unsubscribe (Subscription.js:97) at SafeSubscriber.Subscriber.unsubscribe (Subscriber.js:125) at Subscriber._complete (Subscriber.js:134) at Subscriber.complete (Subscriber.js:115) at Subscriber.wrappedComplete (Subscriber.js:223) at SafeSubscriber.__tryOrUnsub (Subscriber.js:240) at SafeSubscriber.complete (Subscriber.js:225) at FinallySubscriber.Subscriber._complete (Subscriber.js:135) at FinallySubscriber.Subscriber.complete (Subscriber.js:117) at new UnsubscriptionError (UnsubscriptionError.js:18) at SafeSubscriber.Subscription.unsubscribe (Subscription.js:97) at SafeSubscriber.Subscriber.unsubscribe (Subscriber.js:125) at Subscriber._complete (Subscriber.js:134) at Subscriber.complete (Subscriber.js:115) at Subscriber.wrappedComplete (Subscriber.js:223) at SafeSubscriber.__tryOrUnsub (Subscriber.js:240) at SafeSubscriber.complete (Subscriber.js:225) at FinallySubscriber.Subscriber._complete (Subscriber.js:135) at FinallySubscriber.Subscriber.complete (Subscriber.js:117) at resolvePromise (zone.js:809) at eval (zone.js:861) at ZoneDelegate.invokeTask (zone.js:421) at Object.onInvokeTask (core.js:4740) at ZoneDelegate.invokeTask (zone.js:420) at Zone.runTask (zone.js:188) at drainMicroTaskQueue (zone.js:595) at ZoneTask.invokeTask [as invoke] (zone.js:500) at invokeTask (zone.js:1517) at XMLHttpRequest.globalZoneAwareCallback (zone.js:1543)

My Test Code
````
private uploadHeaderImage(file: File) {

const _fileName = uuid();
const _filePath = '/event/' + this.event.detail.rid + '/' + _fileName;

this.log.debug('Uploading image to resource: ', _filePath);

const ref = this.fileStore.ref(_filePath);
const task = this.fileStore.upload(_filePath, file);

this.downloadUrl = ref.getDownloadURL();
this.uploadPercent = task.percentageChanges();
task.snapshotChanges().pipe(
  //finalize(() => this.downloadUrl = ref.getDownloadURL() )
).subscribe();

````

In recent versions we require RXJS 6, https://github.com/ReactiveX/rxjs/blob/master/MIGRATION.md
