And it also includes a default exception handler for it.

To override it, import the `RequestValidationError` and use it with `@app.exception_handler(RequestValidationError)` to decorate the exception handler.

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

  /**
   * Results are posted here as they occur. The find job is done when either one plan completes
   * successfully or all plans fail.
   */
  private val connectResults = taskRunner.backend.decorate(LinkedBlockingDeque<ConnectResult>())

  override fun find(): RealConnection {
    var firstException: IOException? = null
    try {
      while (tcpConnectsInFlight.isNotEmpty() || routePlanner.hasNext()) {

Ve bunun için varsayılan bir exception handler da içerir.

Override etmek için `RequestValidationError`’ı import edin ve exception handler’ı `@app.exception_handler(RequestValidationError)` ile decorate edin.

Exception handler, bir `Request` ve exception’ı alır.

Dans ces cas, au lieu de déclarer un paramètre de *fonction de chemin d'accès* avec `Depends`, vous pouvez ajouter une `list` de `dependencies` au *décorateur de chemin d'accès*.

## Ajouter `dependencies` au *décorateur de chemin d'accès* { #add-dependencies-to-the-path-operation-decorator }

Le *décorateur de chemin d'accès* accepte un argument optionnel `dependencies`.

Il doit s'agir d'une `list` de `Depends()` :

- the response body: le corps de la réponse

- path operation: chemin d'accès
- path operations (plural): chemins d'accès
- path operation function: fonction de chemin d'accès
- path operation decorator: décorateur de chemin d'accès

- path parameter: paramètre de chemin

- the `Request`: `Request` (keep as code identifier)
- the `Response`: `Response` (keep as code identifier)

    * You can have deeply **nested JSON** objects and have them all validated and annotated.
* **Extensible**:
    * Pydantic allows custom data types to be defined or you can extend validation with methods on a model decorated with the validator decorator.

For those cases, instead of declaring a *path operation function* parameter with `Depends`, you can add a `list` of `dependencies` to the *path operation decorator*.

## Add `dependencies` to the *path operation decorator* { #add-dependencies-to-the-path-operation-decorator }

The *path operation decorator* receives an optional argument `dependencies`.

It should be a `list` of `Depends()`:
