Firebug

"firebase": "^8.2.2",

On save image in storage:
My code:

```
import { AngularFireStorage } from '@angular/fire/storage';
constructor(
private fireStorage: AngularFireStorage
) { }

saveIMG(img: File, imgPath: string) {
return this.fireStorage.ref(imgPath)
.put(img);
}
```

Error:

**FirebaseError: Firebase Storage: An unknown error occurred, please check the error payload for server response. (storage/unknown)**

Start by reproducing the upload through AngularFireStorage.ref(imgPath).put(img) with firebase ^8.2.2, using the File and path shown in the report. Inspect the Firebase Storage server response and error payload to determine whether the failure is in AngularFireStorage or Firebase Storage; done means the cause is identified and the upload has a verified resolution or a clearer actionable error.
