# Manipulação de erros

Há diversas situações em que você precisa notificar um erro a um cliente que está utilizando a sua API.

Esse cliente pode ser um browser com um frontend, o código de outra pessoa, um dispositivo IoT, etc.

Pode ser que você precise comunicar ao cliente que:

* O cliente não tem direitos para realizar aquela operação.
* O cliente não tem acesso aquele recurso.
* O item que o cliente está tentando acessar não existe.
* etc.

        if (fessConfig.isValidUserCode(userCode)) {
            return userCode;
        }
        return null;
    }

    /**
     * Deletes the user code cookie from the client browser.
     * This method removes the user identification cookie by setting it to an empty value with zero max age.
     *
     * @param request the HTTP servlet request
     */

These credentials can now be used to perform MinIO API operations.

### Using MinIO Console

- Open MinIO URL on the browser, lets say <http://localhost:9000/>
- Click on `Login with SSO`
- User will be redirected to the Keycloak user login page, upon successful login the user will be redirected to MinIO page and logged in automatically,
