Nodejs 8 - Cannot debug JavaScript via Node.JS (Failed to connect to Standalone V8 VM)

[rajivkanaujia]

First issue is that there is some default setting that is still using --debug and --debug-brk
When I run my simple app, it works. When I try to debug, I get an error on Console

(node:4376) [DEP0062] DeprecationWarning: node --debug and node --debug-brk are invalid. Please use node --inspect or node --inspect-brk instead.

The next step was to force --inspect or --inspect-brk via Preference ---> Nodeclipse. This still does not work.

My js file is simple

var http = require("http");
// create a http server that writes hello world
http.createServer(function(request, response) {
	// Send the HTTP header 
	// HTTP Status: 200 : OK
	// Content Type: text/plain
	response.writeHead(200, {
		'Content-Type' : 'text/plain'
	});

	// Send the response body as "Hello World"
	response.end('Hello World\n');
}).listen(8081);

//Console will print the message
console.log('Server running at http://127.0.0.1:8081/');

When I try to debug this as a Node Application, I get following at Eclipse Console

Debugger listening on ws://127.0.0.1:5858/b1bdf38d-c53a-472d-89f8-6819c5e4c8b1 For help see https://nodejs.org/en/docs/inspector

But then V8 fails. I am not sure where I need to make the changes. Below is the error I get.

Nodeclipse/chromedevtools failed to connect to Standalone V8 VM ( Check Help (F1) and Support http://www.nodeclipse.org/#support ) . Info: Timed out waiting for handshake

I am using Node: v8.1.0 and Eclipse Version: Neon.3 Release (4.6.3) Build id: 20170314-1500

Any suggestions?

See - Nodeclipse/nodeclipse#107

Is there a need for V8 Inspector Protocol for Eclipse?

How is my project build?

[ghost]

I am having this same issue. How to correct this?

[rajivkanaujia]

No fix available. I moved to Visual Studio Code.

[luki2678511]

i got the same issue too, i guess downgrade nodejs 8 to nodejs 6 may be work

[luki2678511]

it's work, downgrade to nodejs v6.12.3 solve

[paulvi]

OK, so it is issue for Nodejs 8+
