Property 'data' does not exist on type 'HttpEvent<Customer>'

I have a setup like this

• api.service (wraps the httpClient Module)
• customer.service

the api service get looks like this:

get<T>(url: string, options?) {
return this.httpClient.get<T>(this.apiUrl + url, this.getOptions(options));}

in my customer.service I have:

    private fetchCustomer(access_token: String): Observable<Customer> {
      const options = { headers: new HttpHeaders({ Authorization: 'Bearer ' + access_token }) };
      return this.http
        .get<Customer>('customers/me', options)
        .map(res => {
          const customer = res.data;
          customer.access_token = access_token;
          return customer;
        })
        .catch(this.handleError.bind(this));
    }

and it give me this error:

[ts]
Property 'data' does not exist on type 'HttpEvent<Customer>'.
Property 'data' does not exist on type 'HttpSentEvent'.

The solution is to use the new way of getting the json data....

const customer = res['data'];
