Selenium Grid Driver.Version Unknown - selenium

Question

I know that this question is asked many times and the answers helped me once.
I used to start as an experiment a Selenium Grid Hub on my local machine and an Node on an other machine. Both were started using parameters on the command line. I was able to start a test so the configuration worked.
Since I do not want to run the hub on my local machine I started is on the same machine as the node but now using JSON config files.
Now I get the WebDriverException: Error forwarding the new session cannot find ... giving the driver.version: unknown error.
I am sure that I pass the version so the error leaves me puzzled.
The node is according to the hub's out put correctly registered. The nodeconfig JSON is:
{
"capabilities":
[
{
"browserName": "chrome",
"maxInstances": 5,
"seleniumProtocol": "WebDriver",
"version": 93,
"platform": "WIN10"
}
],
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"maxSession": 5,
"port": 5555,
"register": true,
"registerCycle": 5000,
"hub": "http://localhost:4444",
"nodeStatusCheckTimeout": 5000,
"nodePolling": 5000,
"role": "node",
"unregisterIfStillDownAfter": 60000,
"downPollingLimit": 2,
"debug": false,
"servlets" : [],
"withoutServlets": [],
"custom": {}
}
The console output in Eclipse shows this error description:
Caused by: org.openqa.selenium.WebDriverException: Error forwarding the new session cannot find : Capabilities {browserName: chrome, goog:chromeOptions: {args: [--headless, --window-size=1920,955, --ignore-certificate-errors, --disable-gpu], extensions: []}, platform: WIN10, version: 93}

The hub show following:
ipy.yyy.yyy.yyy INFO [RequestHandler.process] - Got a request to create a new session: Capabilities {browserName: chrome, goog:chromeOptions: {args: [--headless, --window-size=1920,955, --ignore-certificate-errors, --disable-gpu], extensions: []}, platform: WIN10, version: 93}

The Chrome version on the node is 93.0.4577.82. Do I need to spell this out?
Can anyone give me a clue how to solve this?

Answer 1

All examples on the net are showing version numbers like 93.0 or 93 .
So yes, I had to spell it out like 93.0.4577.82
