Answer 1

Its easy to post an answer when you provide your code instead of a screenshot. Anyhow, you have to pipe it:

getUsers() {
    return this._http.get(this.baseUrl+'/show-users', this.options)
                     .pipe(
                          map((response:Response)=>response.json())
                      );

Remember to import map like this:

import { map } from 'rxjs/operators';

Answer 2

For the latest Version of rxjs we need to install npm install rxjs-compat from terminal then declare

import 'rxjs/add/operator/map';

Answer 3

You can find a solution by using pipe. Here are the steps...

First import map

import {map} from 'rxjs/operators';

Modify your getuser() and other all functions by using pipe

getUser(){
 this._http.get(this.baseUrl+'/show-users', this.options).pipe(map((response:Response)=>response.json()));                
}
