+To customize error response handling, you need to configure the underlying HTTP client.
 
 For `RestClient`:
 
-By default, `RestClient` raises `RestClientException` for 4xx and 5xx HTTP status codes. To customize this, you can register a response status handler that applies to all responses performed through the client:
