## Execution of dependencies with `yield` { #execution-of-dependencies-with-yield }

The sequence of execution is more or less like this diagram. Time flows from top to bottom. And each column is one of the parts interacting or executing code.

```mermaid
sequenceDiagram

participant client as Client
participant handler as Exception handler
participant dep as Dep with yield
participant operation as Path Operation

    * Generando **errores automáticos** devueltos al cliente cuando los datos son inválidos.
* **Documentar** la API usando OpenAPI:
    * Que luego es usada por las interfaces de documentación interactiva automática.

Todo esto puede sonar abstracto. No te preocupes. Verás todo esto en acción en el [Tutorial - Guía del Usuario](tutorial/index.md){.internal-link target=_blank}.

Para declarar un parámetro de query con un tipo de `list`, como en el ejemplo anterior, necesitas usar explícitamente `Query`, de lo contrario sería interpretado como un request body.
