Answer 1

I'm sure you've solved this, but for future visitors:

In Selenium 3, the configuration object has been flattened, as stated here: https://github.com/SeleniumHQ/selenium/wiki/Grid2#configuring-the-nodes-by-json

So you just need to remove configuration. So something like this:

{ "capabilities": [ { "browserName": "chrome", "maxInstances": 5, "seleniumProtocol": "WebDriver" } ], "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy", "maxSession": 5, "port": 5559, "host": ip, "register": true, "registerCycle": 5000, "hubPort": 4445, "hubHost":ip, "hub":"http://XX.XX.XX.XX:XXXX/grid/register", "timeout":600000, "browserTimeout":600000" }

Answer 2

If you look at the complete error message (which you haven't included here)

Exception in thread "main" org.openqa.grid.common.exception.GridConfigurationException: Error with the JSON of the config : Deprecated -nodeConfig file encountered. Please update the file to work with Selenium 3. See https://github.com/SeleniumHQ/selenium/wiki/Grid2#configuring-the-nodes-by-json for more details. at org.openqa.grid.internal.utils.configuration.GridNodeConfiguration.loadFromJSON(GridNodeConfiguration.java:311) at org.openqa.grid.internal.utils.configuration.GridNodeConfiguration.loadFromJSON(GridNodeConfiguration.java:287) at org.openqa.grid.selenium.GridLauncherV3$3.setConfiguration(GridLauncherV3.java:261) at org.openqa.grid.selenium.GridLauncherV3.buildLauncher(GridLauncherV3.java:147) at org.openqa.grid.selenium.GridLauncherV3.main(GridLauncherV3.java:73) Caused by: org.openqa.grid.common.exception.GridConfigurationException: Deprecated -nodeConfig file encountered. Please update the file to work with Selenium 3.

you would realise that the error message also contains info on what you need to do to fix the problem.

Looks like they changed the file format of the node configuration file with 3.0.
