Der Exceptionhandler wird einen `Request` und die Exception entgegennehmen.

{* ../../docs_src/handling_errors/tutorial004.py hl[2,14:16] *}

Wenn Sie nun `/items/foo` besuchen, erhalten Sie statt des Default-JSON-Errors:

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"

The exception handler will receive a `Request` and the exception.

Now, if you go to `/items/foo`, instead of getting the default JSON error with:

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"

_Nothing has changed._
