After making changes in ObjectMapper, Swagger Ui prompts "Unable to infer base url"

In spring boot application after making these changes in objectMapper swagger stops working changes done are below:

@bean
public Jackson2ObjectMapperBuilder jacksonBuilder() {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
builder.featuresToEnable(DeserializationFeature.UNWRAP_ROOT_VALUE);
builder.featuresToEnable(SerializationFeature.WRAP_ROOT_VALUE);
return builder;
}

If I remove these above changes swagger starts working but I need the changes, therefore can not remove. I am using version 2.8.0 of springfox-swagger2. After hitting myost:myport/mycontext/swagger-ui.html call to following endpoints is made:

• http://myhos:8085/mycontext/swagger-resources/configuration/ui response:

{"UiConfiguration":{"apisSorter":"alpha","jsonEditor":false,"showRequestHeaders":false,"deepLinking":true,"displayOperationId":false,"defaultModelsExpandDepth":1,"defaultModelExpandDepth":1,"defaultModelRendering":"example","displayRequestDuration":false,"docExpansion":"none","filter":false,"operationsSorter":"alpha","showExtensions":false,"tagsSorter":"alpha"}}

• http://myhos:8085/mycontext/swagger-resources/configuration/security Respnse:

{"SecurityConfiguration":{}}

• http://myhos:8085/mycontext/swagger-resources Response:

{"List":[{"name":"default","url":"/v2/api-docs","swaggerVersion":"2.0","location":"/v2/api-docs"}]}

Please try with a controller advice like this

@Slf4j
@ControllerAdvice
public class SwaggerResponseAdvice implements ResponseBodyAdvice<Object> {

    @Autowired
    private HttpServletRequest httpServletRequest;

    private final ObjectMapper objectMapper;

    public SwaggerResponseAdvice() {
        objectMapper = new ObjectMapper();
    }

    @Override
    public boolean supports(MethodParameter methodParameter, Class<? extends HttpMessageConverter<?>> aClass) {
        if (httpServletRequest.getRequestURI().equalsIgnoreCase("/v2/api-docs")) {
            return true;
        }
        return httpServletRequest.getRequestURI().startsWith("/swagger-resources");
    }

    @Override
    public Object beforeBodyWrite(Object o, MethodParameter methodParameter, MediaType mediaType, Class<? extends HttpMessageConverter<?>> aClass, ServerHttpRequest serverHttpRequest, ServerHttpResponse serverHttpResponse) {
        try {
            serverHttpResponse.getBody().write(objectMapper.writeValueAsBytes(o));
        } catch (IOException e) {
            log.warn("Error writing from advice", e);
        }
        return null;
    }
}
