service.ts
getLocationData(ids: Array) {
let observableBatch = [];
ids.forEach((id) => {
observableBatch.push(
this.http.get('http://192.168.7.45:9200/location/_doc/'+id)
.map(res => res ));
});
return Observable.forkJoin(observableBatch);
}

this.partDetailsService.getLocationData(this.LocationIds).subscribe(res : Array => {
}

Argument of type 'boolean' is not assignable to parameter of type '(error: any) => void'.ts(2345)
getLocationData(ids: Array) {

    let observableBatch = [];



    this.ids.forEach((id) => {



        observableBatch.push(

              this.http.get('http://192.168.7.45:9200/location/_doc/'+id)

                       .map((res) => res.json()));

    });



    return Observable.forkJoin(observableBatch);

}

this.partDetailsService.getLocationData(locationArr).subscribe(res : Array => {

          this.LocationDetails = res;
error on this line res : Array =>
