ERROR Error: Uncaught (in promise): NullInjectorError: R3InjectorError(AppModule)[AuthGuard -> StorageService -> Storage -> Storage]:

```

here is the service i have created
````
import { Injectable } from '@angular/core';

import { Storage } from '@ionic/storage-angular';

@Injectable({
providedIn: 'root'
})
export class StorageService {
private _storage: Storage;

constructor(private storage: Storage) {
this.init();
}

async init() {
// If using, define drivers here: await this.storage.defineDriver(/*...*/);
const storage = await this.storage.create();
this._storage = storage;
this._storage.set('isAdmin',false);
this._storage.set('token','');
}

// Create and expose methods that users of this service can
// call, for example:
public set(key: string, value: any) {
this._storage?.set(key, value);
}

public get(key: string){
return this._storage?.get(key);
}
}
````

Start with the shown StorageService constructor and the AppModule configuration, then trace how AuthGuard resolves StorageService. Reproduce the reported AuthGuard path and verify that the Storage dependency is registered and the NullInjectorError no longer occurs.
