## Override the default exception handlers { #override-the-default-exception-handlers }

**FastAPI** has some default exception handlers.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

* Added support for network spaces in the kubeapi-load-balancer charm. ([#58708](https://github.com/kubernetes/kubernetes/pull/58708), [@hyperbolic2346](https://github.com/hyperbolic2346))

* Added support for network spaces in the kubernetes-master charm. ([#58704](https://github.com/kubernetes/kubernetes/pull/58704), [@hyperbolic2346](https://github.com/hyperbolic2346))

FastAPI (фактически Starlette) автоматически добавит заголовок Content-Length. Также будет добавлен заголовок Content-Type, основанный на `media_type` и с добавлением charset для текстовых типов.

### `HTMLResponse` { #htmlresponse }

Принимает текст или байты и возвращает HTML-ответ, как описано выше.
