org.openqa.selenium.WebDriverException: unknown error: cannot parse capability: goog:chromeOptions
from unknown error: cannot parse binary
from unknown error: must be a string
  (Driver info: chromedriver=2.33.506106 (8a06c39c4582fbfbab6966dbb1c38a9173bfb1a2),platform=Mac OS X 10.12.6 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 5 milliseconds

Steps to reproduce -

1. Start a hub and a node (previously having ChromeDriver properly configured)

   java -jar selenium-server-standalone-3.8.0.jar -role hub

2. Execute this test.

These are the hub and node logs:

I think the issue could be here:

00:04:04.276 INFO - Capabilities are: Capabilities {browserName: chrome, goog:chromeOptions: {args: [], binary: null, extensions: []}, se:CONFIG_UUID: 25ba6690-d893-4f22-af45-f31...}

Seems that the Chrome options are receiving a null as value for the binary key.

EDIT: I tried again with the grid in Standalone mode, and it works. Seems that it only fails when using hub/node.

Fixed by 7055d6f64c29368092bcb07d606d9605b7ec6247 Version 3.8.1 released with this fix.

[diemol]

Just tested it and it works well. Thanks @barancev

[pradudev]

Thanks @barancev

[sbabcoc]

@barancev - I can't find the 3.8.1 release of selenium-server-standalone. Did this not get deployed?

[lmtierney]

@sbabcoc http://selenium-release.storage.googleapis.com/index.html?path=3.8/

[sbabcoc]

Thanks, @lmtierney ! I'd forgotten that release hierarchy was available. I was expecting that Maven would be able to download the artifact automatically, but it hasn't been released to the public Maven repos.

[barancev]

Version 3.8.1 is available in maven central: http://search.maven.org/#artifactdetails%7Corg.seleniumhq.selenium%7Cselenium-java%7C3.8.1%7Cjar

[barancev]

But, yes, selenium server standalone is not a maven artifact.
