I am trying to get Visual Studio Code to launch webpack's "webpack-dev-server" command, but no matter what configuration I use in launch.json I get an error. 

My current launch.json looks like this:

```
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "node",
            "request": "launch",
            "program": "./node_modules/.bin/webpack-dev-server.cmd",
            "stopOnEntry": false,
            "args": ["-d --hot --inline"],
            "cwd": ".",
            "runtimeExecutable": null,
            "runtimeArgs": [],
            "env": {
                "NODE_ENV": "development"
            },
            "externalConsole": false,
            "sourceMaps": true,
            "outDir": "null"
        },
        {
            "name": "Attach",
            "type": "node",
            "request": "attach",
            "port": 5858
        }
    ]
}

```

Current error is: 

```
cannot launch program 'c:\ftct\node_modules\.bin\webpack-dev-server.cmd'; setting the 'outDir' attribute might help

```

I have tried setting the outDir to some value or other, but it complains about setting this attribute nonetheless.

Any ideas? This is what feels like the final hurdle in my migrating from Visual Studio 2015 to Visual Studio Code!
