Waiting for debugger to disconnect... - Node.js in VSCode

I'm trying to step through a simple javascript example in Visual Studio Code, but the debugger hangs trying to disconnect.

macOS Sierra version 10.12.6

VSCode version 1.18.1 (up to date)

Node.js v8.9.2 (up to date) installed with Homebrew

Debugging with inspector protocol because Node.js v8.9.2 was detected.
node --inspect-brk= /*(port)*/ jsSandbox.js 
Debugger listening on ws:// (ip address)
Debugger attached.
Waiting for the debugger to disconnect...

This seems like it's been a closed issue with both Code and Node already, which is why I'm so confused. Am I doing something wrong?

Here is the only javascript file I'm trying to debug:

// learning about closure

function increase() {  // — gets called once
    var getBig = 0;
    return function() {  // — — gets called each time 
        getBig += 1;      // — — increments each time
        console.log(getBig);
    };
}
var bigOne = increase(); // --  a reference to the instance of the function
bigOne(); //1
bigOne();//2 

...and the project's launch.json config:

        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceFolder}/jsSandbox.js",
            "console": "internalConsole"
        }
