Below is the command written in cmd for registering node:

C:\Program Files (x86)>> node.exe Appium\node_modules\appium\bin\appium.js –address 127.0.0.1 –port 4723 -bp 2252 –udid V00776141045040–nodeconfig E:\firstnode1.json –session-override

What does the error say?

Just as a guess, there are a few things that are iffy to me:

I think the “hub” value should be a complete URL; you might need to add in the protocol for the URL by adding in “http://” to that value.

You need a space separating the udid parameter from the “–nodeconfig” flag.
