[automvc]

The example use springboot 3.0 is normal, but use springboot 3.3 have exception.
Maybe it is different from #31902

example code:

try {
		URI uri = getUri(request, method);

		HttpHeaders headers = new HttpHeaders();
		Enumeration<String> headerNames = request.getHeaderNames();
		//set head from request 
		HttpEntity httpEntity = new HttpEntity<>(body, headers);
		ClientHttpRequestFactory clientHttpRequestFactory = (new SimpleClientHttpRequestFactory() {
		     //... 
		});

		ClientHttpRequestFactory factory = new BufferingClientHttpRequestFactory(clientHttpRequestFactory); // already use BufferingClientHttpRequestFactory

		RestTemplate restTemplate = new RestTemplate(factory);
		ResponseEntity serverResponse = null;

		serverResponse = restTemplate.exchange(uri, method, httpEntity, String.class); //this line have ResourceAccessException : insufficient data written

		// ... other

		logger.error("", e);
	}
	return ResponseEntity.badRequest().build();

please help on this

[rajukosna]

insufficient data written : I/O error on POST request for http://some.com/ this error is coming in using RestTemplate in springboot3.3 version

[bclozel]

@rajukosna we never got the sample we requested.
If you can reproduce the problem with a minimal sample application (something we can git clone or unzip) please create a new issue here: https://github.com/spring-projects/spring-framework/issues

Note: if you cannot reproduce the problem with a minimal sample application this is likely to be a problem specific to your application. In this case please ask a question on StackOverflow.

@bclozel Thank you for your quick response

[rajukosna]

@bclozel
Example code:

ResponseEntity<ResponseDTO> responseEntity = null;
		try {
			LOGGER.info(REST_CALL_FOR_URL);
			if (headers == null) {
				headers = new HttpHeaders();
			}
			headers.add(HEADER_NAME, getFullContextInJson());
			
			HttpEntity<?> httpEntity = new HttpEntity<>(body, headers);
			responseEntity = restTemplate.exchange(UriComponentsBuilder.fromHttpUrl(url).build(true).toUriString(), 
					httpMethod, httpEntity, ResponseDTO.class);
						
			return responseEntity;
		} catch (RestClientException restClientException) {
			logger(restClientException);
			return new ResponseEntity<>(restClientException.getMessage(), HttpStatus.BAD_REQUEST);
		}

ERROR: insufficient data written : I/O error on POST request for "http://localhost:8083/api/o......... ": insufficient data

Thanks for the code snippet but I can't reproduce this issue.

[rajukosna]

@rajukosna We need a complete sample application to be able to help you. That way we know exactly what library versions you're using and how your application is configured. You should also upgrade to 3.3.7 or 3.4.1
