Unable to access variables in Chrome console on OS X

I'm following the tutorial exactly and am able to launch the debugger. There are a few differences though:

  1. In the console, when I open it after I reach the "debugger;" command, I never see the The frontend server is running on port 3000.

  2. My console has two warnings and one error:

    • warning 1: /deep/ combinator is deprecated
    • error 1: Assertion failed: unknown experiment canvasInspection (Runtime.js:358(
    • warning 2: Synchronous XMLHttpRequest on the main thread is deprecated...

  3. On the right in the scope variables box I can see the variables app, posts, etc. and am able to expand them to see their attributes, but if I type "app" into the console I don't get all that detail that is in the video. Instead I get a ReferenceError: app is not defined

Does anyone know what might be the problem? I've done some googling but no luck.

I'll leave this here in case anyone has the same problem. The issue is we aren't opening the chrome console, but instead the node inspector console which is the icon in the top right next to the gear setting.

I had the same problem. Try to call "node-debug src/app.js" instead of "node-inspector src/app.js"
