Я получаю код ошибки несанкционированного доступа 401, даже если имя пользователя и пароль точно такие же, я создал server.js изначально для передачи макетных данных. Я смог войти в систему, используя mock-api, который находится здесьhttp://demo1967295.mockable.io/userauth0 и даже до вызова api он возвращает 500 (внутренняя ошибка сервера), хотя сервер отвечает

Server.js файл, содержащий вызов api, который ранее использовался для передачи макетных данных
