Angular6 Type 'Observable<Object>' is not assignable to type 'Observable<…>'

Context to my problem: I am trying to make an http request in the typescript part of my Angular app. I am just trying to call the localhost:5000 for data from my Python REST API.

I believe the following two components are all that is needed to solve this problem. I just can't see what can be replace or installed to fix this. Please let me know.

exam.model.ts

// TS class to represent coordinate data

export class Exam
constructor(
public Company: string,
public HireDate: string, // should be changed to date
public Title: string,
public Location: string,
public Degree: string,
public yearEnteredWorkForce: string, // should be changed to date
public OfferCostNumber: string,
public bonus: string,
public latitude: number,
public longitude: number
)



exam-api.service.ts

import Injectable from '@angular/core';
import HttpClient, HttpErrorResponse from '@angular/common/http';
import Observable from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import API_URL from '../env';
import Exam from './exam.model';

@Injectable()
export class ExamsApiService any) 'Error: Unable to complete request.');


// GET list of public, future events
getExams(): Observable<Exam>
return this.http
.get(`$API_URL/data`)
.catch(ExamsApiService._handleError);




Here is the entire error I am getting:

ERROR in src/app/http-example/exam-api.service.ts(20,5): error TS2322: Type 'Observable<Object>' is not assignable to type 'Observable<Exam>'.
Type 'Object' is not assignable to type 'Exam'.
The 'Object' type is assignable to very few other types. Did you mean to use the 'any' type instead?
Property 'includes' is missing in type 'Object'.

Above mentioned 'Exam' Class is not assignable to Observable, as class cannot be used a interface.

Make a interface like this :

export interface Exam
Company: string,
HireDate: string,
Title: string,
Location: string,
Degree: string,
yearEnteredWorkForce: string,
OfferCostNumber: string,
bonus: string,
latitude: number,
longitude: number


Then use it in Observable type.

Try This!!, Hope this should help
