[ahmed elbarbary]

I work with angular 7 

I create serice as below

service.ts  

getLocationData(ids: Array<number>) {      
        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);    
    }    

when i call service i get error on definition res as following :

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