Description
When using Spring WebFlux 5.1.8.RELEASE consider having the following code
this.webClient.get()
.uri("http://localhost:" + this.port + "/customstatuscode").retrieve()
.bodyToMono(String.class)
.block();and the controller looks like this
@RequestMapping(value = "/customstatuscode", method = RequestMethod.GET)
public ResponseEntity customStatusCode() {
return ResponseEntity.status(499).build();
}whenever this code is called, an exception is thrown (the stacktrace contains Spring Cloud Sleuth's logic)
org.springframework.web.reactive.function.client.UnknownHttpStatusCodeException: Unknown status code [499]
