No overload matches this call. angular2 to angular12

I am upgrading my Angular-2 project to Angular-12 project and when I changed :

Before

import { Http, Response, Headers } from ‘@angular/http’;

After

import { HttpClient, HttpResponse, HttpHeaders } from ‘@angular/common/http’;

I am facing issue to use HttpHeaders in place of Headers
You can see the images below. I am stuck here. Need some help.

>Solution :

The problem is that you set body in a GET request which has no body!

You can use this code below, but you will have to change your backend to use queryParams:

 this.http.get('myurl', { params: dataObject })
