Hi Harsha,
We also developed a debugging framework for JS using V8 inspector. While
doing that, in between we were also getting this error, but resolved it by
debugging our code.
I can send you the websocket messages that we are getting. Maybe that would
help in some way.
I haven't run your code provided at [https://github.com/hsharsha/v8inspector].
Maybe if you need further help, I can check it.
