Webclient 200 status code with failure in responseBody

I am using webClient to make call to services 1 that call services 2 and then services 2 fetches data from database and returns them. Problem: I have onStatus to catch bad responses, so responses with 400 or 500 status codes. Code Example:

     return webClient.post()
                     .uri('/example')
                     .header('someHeader')
                     .body(PojoBody)
                     .retrieve()
                     .onStatus(HttpStatus:isError, handleError)
                     .bodyToMono(ResponsePojo);

In some edge cases, response is coming with 200 status code and response body has failure message and reason for failure. So how can I retrieve that and then throw an exception with that failure message (in response object returned by other services). Since it tries to map and throws error. Currently I am getting 500 internal server error. Any help will be greatly appreciated thanks.

The onStatus method lets you handle specific HTTP status responses. You can use it for successful responses as well:

  .onStatus(HttpStatus::is2xxSuccessful, this::handleSuccess)
  .onStatus(HttpStatus::isError, this::handleError)
