[IrqValve]

Meta -

OS: Windows 10
Selenium Version: 3.5.0
Browser: Chrome 60.0.3112.90 + ChromeDriver 2.31.488763

At start the test falls without opening a window with a log:
WebDriverException: JSON decoding of remote response failed.
Error code: 4
The response: ''
/home/bazleva/projects-acceptance-tests/vendor/facebook/webdriver/lib/remote/HttpCommandExecutor.php:241

In the driver launch console is:
2017-08-15 12:22:45.137:WARN:osjs.HttpChannel:qtp1562557367-13: /wd/hub/session
java.lang.NullPointerException

And on Selenium Version: 3.4.0 - everything works well without errors.
Can you advise something?

Same issue with .NET 3.5 version.

var driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), DesiredCapabilities.Chrome());
driver.Manage().Window.Maximize();
driver.Quit();

Throws exception:

Duplicate of #4443

[p0deje]

I've missed the fact this is PHP bindings, so re-opening.

[shs96c]

https://github.com/SeleniumHQ/selenium/issues/4461#issuecomment-322465357 is a separate issue, to do with the way that the .Net bindings have set up the w3c payload to New Session.

[shs96c]

I've landed 88e08c8ae0b65970fda25b4b7e28bb862a73155e to address the NPE being thrown.

[unickq]

@shs96c created issue for that - https://github.com/SeleniumHQ/selenium/issues/4465

[barancev]

Version 3.5.3 released that should fix this NPE.
