すると、以下のように `/openapi.json`, `/docs`, `/redoc` のどのURLにアクセスしても、 `404 Not Found` エラーが返ってくるようになります。

```JSON
{
    "detail": "Not Found"
}

Из *операции пути* можно вернуть *элементы перечисления*, даже вложенные в тело JSON (например в `dict`).

Они будут преобразованы в соответствующие значения (в данном случае - строки) перед их возвратом клиенту:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```
Вы отправите клиенту такой JSON-ответ:

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

	localCh := make(chan event.Event, globalAPIConfig.getRequestsPoolCapacity())

	// Convert local messages to JSON and send to mergeCh
	go func() {
		buf := bytes.NewBuffer(grid.GetByteBuffer()[:0])
		enc := json.NewEncoder(buf)
		tmpEvt := struct{ Records []event.Event }{[]event.Event{{}}}
		for {
			select {
			case ev := <-localCh:
				buf.Reset()

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Não Encontrado` como:

```JSON

    "detail": "Not Found"
}
