REST POST works correctly with POSTMAN, but an exception when using Spring RestTemplate

Question

I am writing a Rest client to publish JSON data using Spring RestTemplate. Using POSTMAN and the following JSON data in the body, get the answer correctly -

{
    "InCode":"test",
    "Name":"This is  test",
    "Email":"[e-mail]",
    "Id":18,
}

However, when trying to get into the REST API using Spring RestTemplate as follows

ResponseEntity<String> response = restTemplate.exchange(baseUrl,
                HttpMethod.POST, getHeaders(), String.class);

private HttpEntity<?> getHeaders() throws JSONException {
JSONObject request = new JSONObject();
        request.put("Email", "[e-mail]");
        request.put("Id", "18");
        request.put("Name", "This is  test");
        request.put("InCode", "test");

        headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
        return new HttpEntity<>(request.toString(), headers);
        }

I get an exception -

11:52:56.808 [main] DEBUG o.s.web.client.RestTemplate - Created POST request for "http://server-test/platform/v4/org"
11:52:56.815 [main] DEBUG o.s.web.client.RestTemplate - Setting request Accept header to [text/plain, application/json, application/*+json, */*]

We will be grateful for any help.

Http 500, , , REST. , POSTMAN, REST, reponse.getbody , Byteinputstream, REST String. Spring DefaultResponseErrorHandler.

, DefaultResponseErrorHandler TestHandler :

public class TestErrorHandler extends DefaultResponseErrorHandler {

    @Override
    public void handleError(ClientHttpResponse response) throws IOException {
        //conversion logic for decoding conversion
        ByteArrayInputStream arrayInputStream = (ByteArrayInputStream) response.getBody();
        Scanner scanner = new Scanner(arrayInputStream);
        scanner.useDelimiter("\\Z");
        String data = "";
        if (scanner.hasNext())
            data = scanner.next();
        System.out.println(data);
    }
}

ErrorHandler RestTemplate

RestTemplate restTemplate = new RestTemplate(); 
restTemplate.setErrorHandler(new TestErrorHandler());

, . String.
