Can´t set correctly SDK Instance

[elC0mpa]

Thanks for this awesome library. I am trying to mock AWS Location Services but I haven't done it yet. I am pretty sure the problem is related to the sdk instance

Here is my code:

export class AddressLocatorService {
    private _locationService: AWS.Location;
    private _getAWSPlacesPredictions: (...args: any[]) => Observable<Partial<Address>[]>;

    constructor(
        private _mapsApiLoader: MapsAPILoader,
        private _zone: NgZone,
        private _store: StoreLocation,
        private _http: HttpClient,
        private router: Router
    ) {
	this.initializeAWSLocationService();
}
    private initializeAWSLocationService() {
	const identityPoolId = environment.IDENTITY_POOL_ID
	AWS.config.region = identityPoolId.split(':')[0]
	const credentials = new AWS.CognitoIdentityCredentials({
  		IdentityPoolId: identityPoolId,
	});
	this._locationService = new AWS.Location({credentials, region: AWS.config.region});
	this._getAWSPlacesPredictions = bindCallback(this._locationService.searchPlaceIndexForSuggestions.bind(this._locationService), this._getAutocompletePredictions_callback.bind(this))
    }
}

Nos I will show you the test:

import AWSMock from "aws-sdk-mock";
import AWS from "aws-sdk";

describe("Address Locator Service", () => {
    let service: AddressLocatorService;
    beforeEach(() => {
        TestBed.configureTestingModule({
            //test bed config, doesn´t matter for the issue scope
        service = TestBed.inject(AddressLocatorService);
    });
    it("termSubject should emit correct locations and places", () => {
        AWSMock.setSDKInstance(AWS);//I am pretty sure this is the problem
        AWSMock.mock(
            "Location",
            "searchPlaceIndexForSuggestions",
            (
                params: SearchPlaceIndexForSuggestionsRequest,
                callback: Function
            ) => {
                const data: SearchPlaceIndexForSuggestionsResponse = {
                    Results: [
                        {
                            Text: "52 Tamiami Trl N, Naples, FL 34102-6201, United States",
                            PlaceId:
                                "AQAAAG0AYHn7nsi-sHbgMnoH7_xTw6j7wNCFIXY_1a0jAk1s4bFiozjIT7xmnq8qHBaL7X1tMrR30j5WUK6gqpEyWO8jMNHzBSWSelP481VwonI9ELDNXj9QS8c-LGulU1IBJnLTovC0oDacwPxWnSKgQfeQ-H5Z8zr7uEL3k7WGFujlc0lKgpajpKmMeVWlqI5K",
                        },
                    ],
                    Summary: {
                        DataSource: "Here",
                        Text: "52 tamiami",
                    },
                };
                callback(undefined, data);
            }
        );
        service.termSubject.next('52 tamiami')
        service.dataSource$.subscribe((locationsAndPlaces: Partial<Address>[]) => {
            console.log('Emitted values: ', locationsAndPlaces);
        })
    });

}

The point is that the call to searchPlaceIndexForSuggestions of LocationService is not mocked
I will appreciate any help. Thanks in advance
