Angular proxy to backend not resolved

Trying to fix similar issue, but have no idea why it's not working.

I have API: localhost:8080/api/acl/authorize

Have next http client:

const AUTH_URI = "/api/acl/"

const httpOptions = {
  headers: new HttpHeaders({
      'Content-Type': 'application/json',
      'Access-Control-Allow-Origin': '*'
    }
  )
};

@Injectable({
  providedIn: 'root'
})
export class AuthService {

  constructor(private http: HttpClient) {
  }

  login(credentials: { login: string; passwordHash: string; }): Observable<any> {
    return this.http.post(AUTH_URI + "authorize", {
      login: credentials.login,
      passwordHash: credentials.passwordHash
    }, httpOptions);
  }
}

Add proxy conf:

{
  "/api/acl/authorize": {
    "target": "http://localhost:8080/",
    "secure": false,
    "pathRewrite": {
      "^/api/acl/authorize": ""
    }
  }
}

Starting with proxy option via ng serve --proxy-config proxy.config.json (in packge.json).

Also tried "target": "http://localhost:8080/api/acl/authorize". But still have incorrect request POST http://localhost:4200/api/acl/authorize instead of POST http://localhost:8080/api/acl/authorize

How can I fix this issue?
