Namun bu, `unicorn_exception_handler` tarafından handle edilir.

Böylece HTTP status code’u `418` olan, JSON içeriği şu şekilde temiz bir hata response’u alırsınız:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | Teknik Detaylar

`from starlette.requests import Request` ve `from starlette.responses import JSONResponse` da kullanabilirsiniz.

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

İstemcinizde şöyle bir JSON response alırsınız:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Path İçeren Path Parametreleri { #path-parameters-containing-paths }

Diyelim ki `/files/{file_path}` path'ine sahip bir *path operation*'ınız var.

        NullPointerException exception = assertThrows(NullPointerException.class, () -> {
            smbComTreeDisconnect = new SmbComTreeDisconnect(null);
        });

        // Verify the exception message indicates the config is null
        assertTrue(exception.getMessage().contains("config"));
    }

    /**
     * Test constructor with mock configuration
     */
    @Test

这里，请求 `/unicorns/yolo` 时，路径操作会触发 `UnicornException`。

但该异常将会被 `unicorn_exception_handler` 处理。

你会收到清晰的错误信息，HTTP 状态码为 `418`，JSON 内容如下：

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

也可以使用 `from starlette.requests import Request` 和 `from starlette.responses import JSONResponse`。
