Webdriver is not capturing the http response body

Question

I have enabled the PERFORMANCE logging in my Chrome WebDriver. Its capturing request and response traffic. But the body of the response is missing, capturing only headers, timing info. Response type is Fetch

selenium-java version : 3.6
Driver version : selenium/standalone-chrome:3.8.1

Code snippet is like this,

DesiredCapabilities capabilities = DesiredCapabilities.chrome(); 
LoggingPreferences logPref = new LoggingPreferences();
logPref.enable(LogType.PERFORMANCE, Level.ALL);
capabilities.setCapability(CapabilityType.LOGGING_PREFS, logPref);

Map<String, Object> perfLogPrefs = new HashMap<String, Object>();
perfLogPrefs.put("enableNetwork", true);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("perfLoggingPrefs", perfLogPrefs);
capabilities.setCapability(ChromeOptions.CAPABILITY, options);

WebDriver driver = new RemoteWebDriver(url, getCapabilities())

Response is like this
