first thing suggest upgrade selenium version selenium 3.5.1

there bug in selenium 3.3.1 wherein actual error wouldn't passed on end-user, , stacktrace seems suggest it's perhaps due bug why aren't able see real problem. bug fixed in 3.4.0

once upgrade selenium 3.5.1 in client side, should see problem.

since mentioned chrome, guessing perhaps due fact chromedriver not available in path.

you might want take @ this tutorial wrote on grid, tells set of things required grid , running. have included lot of other information grid in there.
