Pero FastAPI (en realidad Starlette) proporciona una forma más simple de hacerlo que asegura que los middlewares internos manejen errores del servidor y los controladores de excepciones personalizadas funcionen correctamente.

Para eso, usas `app.add_middleware()` (como en el ejemplo para CORS).

```Python
from fastapi import FastAPI

* `$`: ends there, doesn't have any more characters after `fixedquery`.

If you feel lost with all these **"regular expression"** ideas, don't worry. They are a hard topic for many people. You can still do a lot of stuff without needing regular expressions yet.

  + Only use spaces for indentation.
  + Create minimal diffs - disable on save actions like reformat source code or organize imports.
    If you feel the source code should be reformatted, create a separate PR for this change.
  + Check for unnecessary whitespace with `git diff --check` before committing.

Platforms typically extend the features of other platforms to add this support.

By understanding the Gradle platforms and their relationships, you can get a feel for where in the Gradle source tree a particular feature is implemented.

See [Gradle platform architecture](platforms.md) for a list of the platforms and more details.
