You can also combine `dataclasses` with other type annotations to make nested data structures.

In some cases, you might still have to use Pydantic's version of `dataclasses`. For example, if you have errors with the automatically generated API documentation.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares handle server errors and custom exception handlers work properly.

For that, you use `app.add_middleware()` (as in the example for CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()

                    .forEach(path -> {
                        try {
                            Files.delete(path);
                        } catch (IOException e) {
                            // Ignore cleanup errors
                        }
                    });
        }
    }

    @Test
    public void testRequestDurableHandle() {

	adminTestBed.router.ServeHTTP(rec, req)

	t.Logf("HTTP req: %s, resp code: %d, resp body: %s", req.URL.String(), rec.Code, rec.Body.String())

	// Check status code
	if rec.Code != test.wantStatusCode {
		t.Errorf("want status code %d, got %d", test.wantStatusCode, rec.Code)
	}

	// Check returned key list is correct
	if test.wantKeyNames != nil {
		keys := []madmin.KMSKeyInfo{}

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Mas, o FastAPI (na verdade, o Starlette) fornece uma maneira mais simples de fazer isso que garante que os middlewares internos lidem com erros do servidor e que os manipuladores de exceções personalizados funcionem corretamente.

Para isso, você usa `app.add_middleware()` (como no exemplo para CORS).

```Python
from fastapi import FastAPI

And then it just returns a `dict` containing those values.

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

Make sure you [Upgrade the FastAPI version](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} to at least 0.95.1 before using `Annotated`.

        testScriptEngine.register(); // Register again

        // Should still work without errors
        ScriptEngine retrieved = scriptEngineFactory.getScriptEngine("testEngine");
        assertNotNull(retrieved);
        assertEquals(testScriptEngine, retrieved);
    }
