Тепер спробуйте надіслати некоректний елемент, наприклад:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```
Ви отримаєте відповідь, яка повідомить Вам, які саме дані є некоректні у вашому тілі запиту:


```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",

{* ../../docs_src/handling_errors/tutorial005.py hl[14] *}

Jetzt versuchen Sie, einen ungültigen Artikel zu senden:

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

Sie erhalten eine Response, die Ihnen sagt, dass die Daten ungültig sind, und welche den empfangenen Body enthält.

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [

{* ../../docs_src/handling_errors/tutorial005.py hl[14] *}

Ahora intenta enviar un ítem inválido como:

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

Recibirás un response que te dirá que los datos son inválidos conteniendo el body recibido:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",

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"
{
  "detail": [
    {
      "loc": [
        "body",

				if s.walkReadMu != nil {
					s.walkReadMu.Unlock()
				}
				diskHealthCheckOK(ctx, err)
				if err != nil {
					// It is totally possible that xl.meta was overwritten
					// while being concurrently listed at the same time in
					// such scenarios the 'xl.meta' might get truncated
					if !IsErrIgnored(err, io.EOF, io.ErrUnexpectedEOF) {
						internalLogOnceIf(ctx, err, "metacache-walk-read-metadata")
					}

{* ../../docs_src/handling_errors/tutorial005.py hl[14] *}

Now try sending an invalid item like:

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

You will receive a response telling you that the data is invalid containing the received body:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
