Question

Access to fetch at 'http://localhost:8080/contacts/create' from origin 'null' has been

blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. а не подскажите как решается данная проблема? Пытаюсь отправить данные с фронта на бэк и вылезает такая ошибка
