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

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": [

Exception { public void EncoderException(String); } org/apache/commons/codec/language/Metaphone.class package org.apache.commons.codec.language; public synchronized class Metaphone implements org.apache.commons.codec.StringEncoder { private String vowels; private String frontv; private String varson; private int maxCodeLen; public void Metaphone(); public String metaphone(String); public Object encode(Object) throws org.apache.commons.codec.EncoderException; public String encode(String) throws or...

Examples of valid array, slice, and map literals:

<pre>
// list of prime numbers
primes := []int{2, 3, 5, 7, 9, 2147483647}

// vowels[ch] is true if ch is a vowel
vowels := [128]bool{'a': true, 'e': true, 'i': true, 'o': true, 'u': true, 'y': true}

// the array [10]float32{-1, 0, 0, 0, -0.1, -0.1, 0, 0, 0, -1}
filter := [10]float32{-1, 4: -0.1, -0.1, 9: -1}

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

受信したボディを含むデータが無効であることを示すレスポンスが表示されます:

```JSON hl_lines="12 13 14 15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
