Connection Prematurely closed BEFORE Response when setting spring.codec.max-in-memory-size
jelbatnigi opened this issue · comments
I have a WebClient that makes a get request and the response exceeds the default 265KB in Springboot. So when the call is made I get the exception that Buffer size has been exceded.
Now When I set the max memory size say to 6000KB and make the get request I get the exception
org.springframework.web.reactive.function.client.WebClientRequestException: Connection prematurely closed BEFORE response; nested exception is reactor.netty.http.client.PrematureCloseException: Connection prematurely closed BEFORE response
final ExchangeStrategies strategies = ExchangeStrategies.builder()
.codecs(codecs -> codecs.defaultCodecs().maxInMemorySize(6000 * 1024))
.build();
HttpClient httpClient = HttpClient.create()
.responseTimeout(Duration.ofSeconds(60)).option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 600000).option(ChannelOption.SO_KEEPALIVE, true);
WebClient web = WebClient.builder().exchangeStrategies(strategies).clientConnector(new ReactorClientHttpConnector(httpClient)).build();
return web.get().uri("/{uri}/" + id).headers(httpHeaders -> httpHeaders.setBearerAuth(getToken()))
.header("requestId", requestId)
.header("type", typeHeaderValue.toString())
.retrieve()
.onStatus(HttpStatus::is4xxClientError, clientResponse -> Mono.error(new WebClientException("Client Error for getStatusUpdate()")))
.onStatus(HttpStatus::is5xxServerError, clientResponse -> Mono.error(new WebServerException("Server Error for getStatusUpdate()")))
.bodyToMono(String.class).blockOptional();
I have contacted the team on the server side and they are not seeing the request making it.
I am new to Webflux I have been using RestTemplate. What am I missing here? why the connection gets terminated when I set the max-memory-size (Doesn't matter to which value I set it to)? Is there any additional configurations related to connection provider that I have to make?
Any help in the right direction is appreciated.
Thanks
@jelbatnigi Please provide logs when you reproduce the issue + tcpdump.
Unfortunately Security blocks tcpdump. I am going to try and get you that But this is what I see in my logs on the client side. I don't know what the server side logs are showing

@jelbatnigi This exception is Connection refused and not Connection Prematurely closed BEFORE Response or I miss something?
@jelbatnigi I'm closing this one. We can reopen it when there is more information.
I have the same problem, below is my exception.
