How to get Xdebug working with Visual Studio Code?

So I’m trying to get VS Code working with XDebug, like all the cool kids, but I’m failing miserably.

I’ve installed all the appropriate extensions as above and I think I have my launch.json set up correctly.

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
    {
        "name": "Listen for XDebug",
        "type": "php",
        "request": "launch",
        "port": 9000,
        "pathMappings": {
            "/var/www/html": "${workspaceRoot}",
            "/app/public": "/Users/afragen/Local%20Sites/single/app/public/"
        }
     },
    {
        "name": "Launch currently open script",
        "type": "php",
        "request": "launch",
        "program": "${file}",
        "cwd": "${fileDirname}",
        "port": 9000
    }
]
}

I’ve restarted everything and still I don’t stop on a breakpoint.

FWIW, everything does work in PhpStorm.

Any ideas?
