Each event is a small text block with "fields" like `data`, `event`, `id`, and `retry`, separated by blank lines.

It looks like this:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

SSE is commonly used for AI chat streaming, live notifications, logs and observability, and other cases where the server pushes updates to the client.

Then we use the request directly, and extract the body as `bytes`. This means that FastAPI won't even try to parse the request payload as JSON.

And then in our code, we parse that YAML content directly, and then we are again using the same Pydantic model to validate the YAML content:

     * <li>If the system class loader can be obtained, that class loader</li>
     * </ol>
     * <p>
     * However, if both the class loader that loaded the target class and the class loader that loaded this class can be obtained,
     * and the class loader that loaded the target class is an ancestor of the class loader that loaded this class,
     * the class loader that loaded this class is returned.
     * </p>
