These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

### Override request validation exceptions { #override-request-validation-exceptions }

When a request contains invalid data, **FastAPI** internally raises a `RequestValidationError`.

And it also includes a default exception handler for it.

                .orElseThrow(() -> new SsoMessageException(
                        messages -> messages.addErrorsFailedToProcessSsoRequest(UserMessages.GLOBAL_PROPERTY_KEY, "Invalid state."),
                        "Failed to process metadata.", new SsoProcessException("Invalid state.")));
    }

    /**
     * Gets the logout response.
     * @return The logout response.

			}
		}
		if i := strings.Index(host, "%"); i > -1 {
			host = host[:i]
		}

		if host == "" {
			return ep, fmt.Errorf("invalid URL endpoint format: empty host name")
		}

    }

This will also work because `RedirectResponse` is a subclass of `Response`, and FastAPI will automatically handle this simple case.
