Http Client Angular 6

Question

I'm trying to type the return of my request however I'm getting the following error:

Type 'Observable' is not assignable to type 'Observable'. Type 'ArrayBuffer' is missing the following properties from type 'AccountModel[]': length, pop, push, concat, and 25 more

I request is as follows:

 getAccounts(): Observable<AccountModel[]>
    {
        return this.http.get(`${this._configShared.getApiUrl()}`, this.httpOptions);
    }

Where am I going wrong?

Thanks in advance...

I did the following and it also did not work:

getAccounts(): Observable<AccountModel[]>
    {
        return this.http.get<AccountModel[]>(`${this._configShared.getApiUrl()}`, this.httpOptions);
    }

error:

Type 'Observable>' is not assignable to type 'Observable'. Type 'HttpEvent' is not assignable to type 'AccountModel[]'. Type 'HttpSentEvent' is missing the following properties from type 'AccountModel[]': length, pop, push, concat, and 26 more.

Change

return this.http.get(`${this._configShared.getApiUrl()}`, this.httpOptions);

to

return this.http.get<AccountModel[]>(`${this._configShared.getApiUrl()}`, this.httpOptions);
