Quando importo:
import ‘rxjs/add/operator/toPromise’;
Não aparece nenhum erro no vs code, mas aparece o seguinte erro no log do angular-cli ao executar ng serve:
ERROR in ./src/app/lancamentos/lancamento.service.ts
Module not found: Error: Can’t resolve ‘rxjs/add/operator/toPromise’ in '/home/demys/algaworks/algamoney-ui/src/app/lancamentos’
｢wdm｣: Failed to compile.
Já verifiquei o caminho na pasta node_modules e está OK.
Ao remover o import ‘rxjs/add/operator/toPromise’;
o projeto inicia normalmente mas ao acessar a api rest aparece o seguinte erro no console do chrome:
XMLHttpRequest cannot load http://localhost:8080/lancamentos?resumo. Response for preflight has invalid HTTP status code 401
ERROR Error: Uncaught (in promise): Response with status: 0 for URL: null(…)
Testei a api com postman e está OK.
Como corrigir esse erro?
