## Override the default exception handlers { #override-the-default-exception-handlers }

**FastAPI** has some default exception handlers.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

   *     Stream.of("banana", "apple", "carrot", "asparagus", "cherry")
   *         .collect(
   *             flatteningToImmutableSetMultimap(
   *                  str -> str.charAt(0),
   *                  str -> str.substring(1).chars().mapToObj(c -> (char) c));
   *
   * // is equivalent to
   *
   * static final ImmutableSetMultimap<Character, Character> FIRST_LETTER_MULTIMAP =

When you do this, the examples will be part of the internal **JSON Schema** for that body data.

Nevertheless, at the <dfn title="2023-08-26">time of writing this</dfn>, Swagger UI, the tool in charge of showing the docs UI, doesn't support showing multiple examples for the data in **JSON Schema**. But read below for a workaround.

### OpenAPI-specific `examples` { #openapi-specific-examples }

C'est presque la seule chose que vous devez vous rappeler de faire correctement vous‑même pour être conforme aux spécifications.

Pour le reste, **FastAPI** s'en charge pour vous.

### Dépendances avec `yield` et `scope` { #dependencies-with-yield-and-scope }

Dans la version 0.121.0, **FastAPI** a ajouté la prise en charge de `Depends(scope="function")` pour les dépendances avec `yield`.
