Cannot debug Nodejs with node-inspector: websocket_closed and Assertion failed: Unknown experiment canvasInspection

Question

I try to debug my server.js app with node-inspector (v0.12.8), nodejs (v5.9.1) and chrome (v49.0.2623.112 m) under windows environment.
In a shell i do

node-inspector   
Node Inspector v0.12.8 Visit http://127.0.0.1:8080/?port=5858 to start debugging.

In a second shell i do

node --debug server.js

When i go to chrome tab i obtain a message:

Detached from target
remote debug has been terminated with reason: websocket_closed
please reattach to the new target

In the console dev tool of chrome i can see either a message that inspector can't find experimental function canvasInspection (removed in the latest chrome version).
I'm doing something wrong?

Answer 1

I had the same problem, I fixed it the way below:

1- Go and edit the following file in your currently in use nodejs path:

 ...\node_modules\node-inspector\lib\InjectorClient.js

2- Go to line 111. if you're using vim as text editor you can do it by command :111

3- Add the following if statement at line 111 and indent the next line.

if(NM.length > 0) 
  cb(error, NM[0].ref);

4- Save and re-run node-inspector.

Cheers!

I'm using MacOS Sierra, Node v6.3.1. But the solution is general.
