Webdriver没有捕获http响应正文

Question

我已在Chrome WebDriver中启用了PERFORMANCE日志记录。它的捕获请求和响应流量。但是响应的主体丢失了，只捕获了标题，时间信息。响应类型为Fetch

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

代码段就是这样，

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())

响应是这样的
