...це не працює, тому що тип анотації не є типом Pydantic і не є просто класом `Response` або його підкласом, а є об’єднанням (union) — або `Response`, або `dict`.

### Create it { #create-it }

Create a file `main.py` with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

		POLICY_INFO_SERVER_ROLE    = 6,
		POLICY_INFO_MODIFICATION   = 9,
		POLICY_INFO_DNS_DOMAIN     = 12
	};

	typedef [switch_type(short)] union {
		[case(POLICY_INFO_ACCOUNT_DOMAIN)] LsarDomainInfo account_domain;
		[case(POLICY_INFO_DNS_DOMAIN)] LsarDnsDomainInfo dns_domain;
	} LsarPolicyInfo;

	typedef struct {
		sid_t *sid;
	} LsarSidPtr;

		POLICY_INFO_PRIMARY_DOMAIN = 3,

		POLICY_INFO_DNS_DOMAIN     = 12
	};

	typedef [switch_type(short)] union {
		[case(POLICY_INFO_ACCOUNT_DOMAIN)] LsarDomainInfo account_domain;
		[case(POLICY_INFO_DNS_DOMAIN)] LsarDnsDomainInfo dns_domain;
	} LsarPolicyInfo;

	typedef struct {

Das gleiche wird passieren, wenn Sie eine <abbr title="Eine Union mehrerer Typen bedeutet: „Irgendeiner dieser Typen“">Union</abbr> mehrerer Typen haben, und einer oder mehrere sind nicht gültige Pydantic-Typen. Zum Beispiel funktioniert folgendes nicht 💥:
