Please advice

This is because of SeleniumHQ/selenium#6275 Selenium grid is not taking

"custom": { "grid_extras_port": 3000 },

properly. If one removes it it works

-jar-with-dependencies.jar;\tmp\webdriver\3.14.0.jar
When i installed webdriver with 3.11.0 it is working fine.

[shankarkc]

But I want to move to latest webdriver and browsers. So this issue is a blocker for that.

[leonkatz]

How do I fix this on the node? The hub starts up but the node will not, because the custom property is copied over.

[denis-platonov]

As mentioned earlier, it is because of SeleniumHQ/selenium#6275, so just transform port number to string type:
"custom": { "grid_extras_port": "3000" },
Worked for me
