### Bug or Regression

    /** The key of the message: Invalid Request Format. */
    public static final String LABELS_request_error_title = "{labels.request_error_title}";

    /** The key of the message: Your request to the URL is invalid. */
    public static final String LABELS_bad_request = "{labels.bad_request}";

* Action required: federation-only: Please update your cluster name to be a valid DNS label. ([#30956](https://github.com/kubernetes/kubernetes/pull/30956), [@nikhiljindal](https://github.com/nikhiljindal))
    * Updating federation.v1beta1.Cluster API to disallow subdomains as valid cluster names. Only DNS labels are allowed as valid cluster names now.

and is written in assembly source as <code>AND</code>.
The enumeration is mostly in alphabetical order.
(The architecture-independent <code>AXXX</code>, defined in the
<code>cmd/internal/obj</code> package,
represents an invalid instruction).
The sequence of the <code>A</code> names has nothing to do with the actual
encoding of the machine instructions.
The <code>cmd/internal/obj</code> package takes care of that detail.

    not send the `Expect: continue` request header.
 *  Fix: Do not count web sockets toward the dispatcher's per-host connection
    limit.
 *  Fix: Avoid using invalid HTTPS sessions. This prevents OkHttp from crashing
    with the error, `Unexpected TLS version: NONE`.
 *  Fix: Don't corrupt the response cache when a 304 (Not Modified) response

			n:            27,
			want:         26,
			wantErr:      io.EOF,
			wantBuffered: 0,
		},
		// Any error from filling shouldn't show up until we
		// get past the valid bytes. Here we return 5 valid bytes at the same time
		// as an error, but test that we don't see the error from Discard.

O `RequestValidationError` contém o `body` que ele recebeu de dados inválidos.

Você pode utilizá-lo enquanto desenvolve seu app para conectar o *body* e debugá-lo, e assim retorná-lo ao usuário, etc.

Tente enviar um item inválido como este:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Você receberá uma *response* informando-o de que a data é inválida, e contendo o *body* recebido:

```JSON hl_lines="12-15"

    * `kubectl proxy --www` now logs a warning when the dir is invalid  ([#44952](https://github.com/kubernetes/kubernetes/pull/44952), [@CaoShuFeng](https://github.com/CaoShuFeng))

- Simplied validation error message for invalid fields by removing redundant field name. ([#132513](https://github.com/kubernetes/kubernetes/pull/132513), [@xiaoweim](https://github.com/xiaoweim)) [SIG API Machinery, Apps, Auth, Node and Scheduling]
