### Use the `RequestValidationError` body

The `RequestValidationError` contains the `body` it received with invalid data.

You could use it while developing your app to log the body and debug it, return it to the user, etc.

```Python hl_lines="14"
{!../../docs_src/handling_errors/tutorial005.py!}
```

Now try sending an invalid item like:

```JSON
{
  "title": "towel",

Note that as a new builtin command, `kubectl debug` takes priority over any `kubectl` plugin named “debug”. You will need to rename the affected plugin.
Invocations using `kubectl alpha debug` are now deprecated and will be removed in a subsequent release. Update your scripts to use `kubectl debug` instead of `kubectl alpha debug`!

Nas versões anteriores do Python, você poderia utilizar threads ou <a href="http://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. Mas o código é um pouco mais complexo de entender, debugar, e pensar sobre.

Nas versões anteriores do NodeJS / Navegador JavaScript, você poderia utilizar "callbacks". O que leva ao  <a href="http://callbackhell.com/" class="external-link" target="_blank">inferno do callback</a>.
