I integrated bluetooth component and battery level service into my angular project. When I run ng serve --open, I get below errors. Could you please give some comments for the root causes?

ERROR in src/app/bluetooth.service.ts(24,37): error TS2339: Property 'map' does not exist on type 'Observable'. src/app/bluetooth.service.ts(43,10): error TS2339: Property 'mergeMap' does not exist on type 'Observable<void | BluetoothRemoteGATTServer>'.

solved by change import part in service.ts file to:

import { Observable } from 'rxjs'; import { map, mergeMap } from 'rxjs/operators';
