После этого, если перейти по адресам `/openapi.json`, `/docs` или `/redoc`, вы получите ошибку `404 Not Found`, например:

```JSON
{
    "detail": "Not Found"
}

                return false;
            }

            final Map<String, Object> result = parseJson(response.getContentAsString());
            final Boolean found = (Boolean) result.get("found");
            if (found == null || !found) {
                return false;
            }

            final Map<String, Object> source = getMapValue(result, "_source");
            if (source == null) {

```

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON
{
    "detail": "Not Found"
}

        assertTrue(mockFilterChain.wasDoFilterCalled());
        assertFalse(corsHandlerFactory.wasGetCalled());
    }

    // Test with valid Origin but no CorsHandler found
    @Test
    public void test_doFilter_noCorsHandler() throws IOException, ServletException {
        mockRequest.setHeader("Origin", "http://example.com");
        corsHandlerFactory.setHandler(null);
