Cada um desses `dict` de retorno pode ter uma chave `model`, contendo um modelo do Pydantic, assim como o `response_model`.

O **FastAPI** pegará este modelo, gerará o esquema JSON dele e incluirá no local correto do OpenAPI.

Por exemplo, para declarar um outro retorno com o status code `404` e um modelo do Pydantic chamado `Message`, você pode escrever:

```Python hl_lines="18  22"

    const data = await response.json()
    return data
}

async function getData() {
    let page = 1
    let data = []
    let dataBatch = await getDataBatch(page)
    data = data.concat(dataBatch.items)
    const totalCount = dataBatch.total_count
    while (data.length < totalCount) {

        StringWriter sw = new StringWriter();
        properties.save(sw);
        String msg = sw.toString();
        assertTrue(sw.toString().endsWith(RESULT3), msg);
        List<String> rawValue = properties.getRaw(KEY1);
        assertEquals(2, (Object) rawValue.size());
        assertEquals(KEY1A + " = " + VALUE1, rawValue.get(0));
        assertEquals(VALUE1, rawValue.get(1));
    }

    @Test

    static CollectStepData lookupCollectStepData(RequestTrace trace) {
        CollectStepData collectStepTrace = null;
        while (trace != null) {
            if (trace.getData() instanceof CollectStepData) {
                collectStepTrace = (CollectStepData) trace.getData();
                break;
            }
            trace = trace.getParent();
        }
        return collectStepTrace;
    }

        final Map<String, Object> searchBody = new HashMap<>();
        String response = checkGetMethod(searchBody, "").asString();
        final Map<String, Object> res = JsonPath.from(response).getMap("response.setting");
        assertTrue(res.containsKey("total_words_num"));
        assertTrue(res.containsKey("document_words_num"));
        assertTrue(res.containsKey("query_words_num"));
