Но оно будет обработано `unicorn_exception_handler`.

Таким образом, вы получите чистую ошибку с кодом состояния HTTP `418` и содержимым JSON:

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

/// note | Технические детали

Также можно использовать `from starlette.requests import Request` и `from starlette.responses import JSONResponse`.

        private final AtomicLong latencyTotal = new AtomicLong();
        
        public double getAverageLatency() {
            long ops = operations.get();
            if (ops == 0) return 0;
            return (double) latencyTotal.get() / ops;
        }
        
        public long getThroughput() {
            return bytesSent.get() + bytesReceived.get();
        }
    }
    

But it will be handled by the `unicorn_exception_handler`.

So, you will receive a clean error, with an HTTP status code of `418` and a JSON content of:

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