Now, get the user data from the (fake) database, using the `username` from the form field.

If there is no such user, we return an error saying "Incorrect username or password".

For the error, we use the exception `HTTPException`:

=== "Python 3.10+"

    ```Python hl_lines="3  79-81"
    {!> ../../../docs_src/security/tutorial003_an_py310.py!}
    ```

  // empty there is no information available.
  // +optional
  optional string reason = 1;

  // A human-readable description of the cause of the error.  This field may be
  // presented as-is to a reader.
  // +optional
  optional string message = 2;

  // The field of the resource that has caused this error, as named by its JSON

Os status codes na faixa dos 400 significam que houve um erro por parte do cliente.

Você se lembra de todos aqueles erros (e piadas) a respeito do "**404 Not Found**"?

## Use o `HTTPException`

Para retornar ao cliente *responses* HTTP com erros, use o `HTTPException`.

### Import `HTTPException`

```Python hl_lines="1"

            firDiagnostic as KtPsiDiagnostic,
            token,
        )
    }
    add(FirErrors.NEW_INFERENCE_ERROR) { firDiagnostic ->

            firDiagnostic as KtPsiDiagnostic,
            token,
        )
    }
    add(FirErrors.OTHER_ERROR) { firDiagnostic ->
